Some Legal Matters. ------------------- You have now available the Public Domain version of the general purpose measurement data processor Profile. This software may not be distributed commercially, that is, for more than the cost of distribution. However, non-commercial copying of this program package (for example by non-profit organizations, computer user groups, bulletin board systems or private users) is encouraged. In other words: Copy Freely, But Do Not Sell. You are strongly urged to distribute this software in its original form. That is a compressed archive file called PROFILE.ARC. It contains not only the executable program, but also the help file, further documentation and several example Profile programs. If you don't copy the ARC file, at least copy all files that were spawned from it. Every care has been taken to ensure that the Profile package operates properly. We however make no warranties, explicit or implied, that it is free of error. If you use Profile to solve a problem whose incorrect solution might injure people or damage property, you do so at your own risk. By using Profile you agree to the terms above. You also agree that the author and the Delft University of Technology will not be held liable for any cost you may incur, or potential income you might lose as a result of using Profile. 2. A 250 Word Introduction To Profile. ----------------------------------- PRINCIPLE Separation of measurement data acquisition from measurement data interpretation PURPOSE 1. Relief the developer of (electrical) measurements from computer programming (as much as possible) by providing - Standard measurement data interpretation tools - Data I/O and graphical facilities - Hooks for easy add-on of problem specific software 2. Provide an environment for parameter extraction by nonlinear optimization ("Inverse Modelling") SCOPE - Both interactive and programmable use (like BASIC) - Free expression definition and evaluation (all math functions) Even use as a pocket calculator! - History mechanism and command line editting - Integration, Differentiation, Curve-Fit - Various data transformations (e.g. Map of data to another x-axis) - Nonlinear parameter extraction with the Levenberg-Marquardt method - File I/O + fast graphical output on various devices (HP Plotter, IBM-PC, Tek4010, VT100, line printer) - 2D Version Prof2d with contour plots (in a separate .arc file) - On-line help and 150 page manual - Written in portable C - Available on the IBM-PC, VAX/VMS and various UNIX systems AVAILABILITY - This Public Domain Profile IBM-PC executable may be copied freely. - The Profile/Prof2d source code, User's Manual and IBM-PC and VAX/VMS executables are available against handling cost from the Electrical Materials Laboratory of the Delft University of Technology. A license agreement then must be signed. A suitable request form is included as a part of this file. Note that a sister program, Prof2d, is also available in the public domain (as PROF2D.ARC) against the same conditions. This is a 2D data processor with contour plots on both the PC screen and HP-GL plotters. The two programs share large parts of the same source code. 3. A 1000 Word Introduction to Profile. ------------------------------------ Profile and Prof2d are computer programs that have evolved from the impurity profiling project which is being carried out at the Electrical Materials Laboratory of the Delft University of Technology. However, their scope goes beyond impurity profiling. With Profile and Prof2d, any measured or simulated data can be read, processed, plotted, written and even generated, provided that the format in which the data is supplied or needed conforms to some simple standards. The usefulness of the two programs is much enhanced by the fact that any mathematical expression, containing measurement data and other, user specified data, can be executed. Many mathematical functions are provided by the programs. Profile and Prof2d even can be used as an on-line pocket calculator. A sequence of data processing commands and expressions can be saved or prepared in advance in a separate file and executed as a program by Profile and Prof2d. This allows use of the same data processing scheme on many different data. Profile is a program that can be used to process data, obtained by measurements of simulations or otherwise, fast and flexibly. A major constraint is that data has to be to be available in text files, and organized columnwise. Profile can also generate columnwise organized data files by evaluation of functions. Profile operates as a command interpreter. When invoked it prompts with prof> and to this prompt commands and expressions may be typed. A command tells Profile to do something with the data (read it, write it, perform a numerical transformation, make a plot, etc). An expression is a mathematical formula that tells Profile to compute new data using data already present. prof> diff num ydata xdata dydx or prof> y2=ln(x2/pi) Data is present in the form of scalars (variables) and 1D vectors (data types or 'columns'). The names of the variables and data types must be declared to Profile using the commands type and var. All data is represented by double precision floating point notation. If a command operates on an undetermined number of data types or variables, it usually ends in a dollar sign '$', that indicates the end of data names: prof> print a1 a2 a3 a4 $ If however Profile knows in advance how many names will be given, the dollar sign is not required: prof> fit idrain vgate idrfit When giving commands, Profile asks for more data until it is satisfied. E.g., if you only type the command name fit, it will ask for the names of the appropriate data types: prof> fit y data type: idrain x data type: vgate fitted y data type: idrfit Hence, in case you are unsure, just give the command name. Help on all commands, and on a number of topics of general interest, is available by giving prof> help <keyword> A list of possible keywords is displayed if you give prof> help help Most MS-DOS commands can be executed directly without leaving the program Profile. This allows you to use e.g. the system editor for changing data in files whilst using the Profile package. prof> edit data.dat prof> get data.dat x y z $ A variety of graphical output can be generated using Profile. In the first place, with the command graph it is possible to make a plot on the computer line printer using alpha-numerical characters only. The size of this plot is user controlled. In the second place, with plot it is possible to produce a much nicer plot on pen plotters that use HP-GL as an graphical language. This has been tested for the much used HP7475/HP7550A eight color pen plotters. Thirdly, plots may be previewed on the terminal or PC screen using the command view. Profile knows several terminal protocols (including VT100, VT52, CIT101 alternate graphics and IBM-PC graphics) and is able to draw a graph of acceptable resolution on ordinary video terminals such as the DEC VT100. A series of Profile commands may be saved in a file and executed as a Profile 'program'. This can even be done on line using the command exec. prof> exec subrout.pro This makes it possible to use previously defined data processing sequences (comparable to subroutines in programming languages). Exec statements may be nested, allowing an hierarchical program structure. The Modified Damped Least Squares non-linear parameter optimization method, an improved variant of the Levenberg-Marquardt method, is available through the command levmar. This allows the iterative determination of the (non-linear) parameters of a (non-linear) model that describes some measurement data. This model may be either an internal analytical expression (previously defined) or an external program that reads the parameters and simulates the measurement.

A 150 page User's Manual is available (together with the source code and PC and VAX/VMS executables) from the Electrical Materials Laboratory of the Delft University of Technology by license agreement. More information is provided in section 5. of this documentation. A provisional manual can be obtained by printing the contents of the file with help texts called PROF.HEL that is bundled with the Public Domain Profile version. 4. Installation of Public Domain Profile on the IBM-PC. ---------------------------------------------------- This Public Domain version of Profile runs on the IBM-PC and true compatibles. It benefits greatly from a mathematical co-processor, but it executes without one. It will drive the CGA, EGA, VGA, Hercules and Olivetti (AT&T 6300) graphics adaptors. These are recognized automatically. If for some reason the wrong adaptor is detected, you may use set a graphics adaptor type with the command <adapt>. From the PROFILE.ARC file you have obtained a PROF.EXE file. If you have a hard disk, you should put this in a directory that is in your search path (see MS-DOS command PATH). Profile may use two auxiliary files, PROF.MES and PROF.HEL. The PROF.HEL file contains the help texts shown when using the command help. The content of the PROF.MES file is printed each time Profile is invoked. Only the PROF.HEL file is bundled with Public Domain Profile. If you want, you can create your own PROF.MES. By default, Profile expect these files to be present in a directory called C:\EXTRA. You can either create such a directory or use the run time option -d (see also the invoke help page) to state the help files directory. It may be a good idea to create a prof.bat file in your usual directory with executable programs. This file should contain a single line like (if the program resides in directory C:\PROGS and the helpfiles in directory C:\HELPFILES) C:\PROGS\PROF.EXE -dC:\HELPFILES %1 %2 If you do not have a hard disk, you will need option -d to tell the programs that the helpfiles are on disk A: or B: and invoke by A> prof -dA: <- search on disk A: A> prof -d <- search in current directory Finally, Profile also finds the help file if it is in the current directory. Some Profile example programs are included with in the Public Domain distribution file. You may execute such a program by typing: C> prof example1.pro <enter> Plots can be made by connecting a HP7550A or compatible plotter to the IBM-PC serial port (COM1). A cable fit for hardwired RS232 handshaking should be used. The baud rate of the plotter should be equal to the baud rate set for the PC's serial port with the MS-DOS command mode. For each handshaking sequence a dot (.) is printed on the screen. Setting the RS232 port's baud rate to (e.g.) 4800 b/s: C> mode com1:48 The following HP7550A plotter settings are suggested: Main menu: Monitor mode: off Standard (not enhanced) Serial menu: Dataflow: remote, standalone Bypass: off Handshake: hardwired, direct Duplex: full Parity: 8 bits off Baud: As set by MS-DOS command mode 5. How to obtain the Profile/Prof2d sources and further executables. ----------------------------------------------------------------- The Profile Public Domain version you now have is limited in several ways: - Public Domain notices are given in the graphical output - The external model of the optimization driver has been disabled - No object files are available, hence no user written code can be linked to add user specific data interpretation software. Profile is written in portable C and runs on various computer systems, including the IBM-PC, VAX/VMS and several UNIX dialects. You can acquire a printed manual, non Public Domain executables for the VAX and the PC and the source code by signing a licence agreement with the Faculty of Electrical Engineering of the Delft University of Technology. Send a written request, stating the desired magnetic carrier, to dr. Wim Crans Electrical Materials Laboratory Delft University of Technology P.O. Box 5031, Mekelweg 4 2600 GA DELFT THE NETHERLANDS Fax: +31-15-783622 Telex 38151 butud nl You will then be sent the appropiate licence forms. After shipment of the manual and the software you will be billed for the handling cost, estimated to be US $50 or Dfl. 100,--, unless you enclose a check for that amount. A suitable software request form is included underneath. Good news for Delft University Users: you do not need a licence agreement. The manual and executables can be ordered at the above address using an internal order form. The exchange of the source code is negotiable. 6.
