- DAN is a graphically oriented scientific data analysis tool for IBM PCs
- and compatibles. It provides a quick and flexible means of processing
- data files by allowing these files to be used as variables in formulas.
- DAN treats them as if they defined continuous mathematical functions.
-
- DAN lets you define and execute special processing algorithms to
- manipulate data and produce plots, disk files, and/or listings of the
- processed data. A processing algorithm is expressed as a sequence of
- statements whose syntax is similar to a high level language but without
- most of the housekeeping details associated with programming.
- Algorithms may be created, saved, and used as needed.
-
- Data manipulations are specified by combining arithmetic operators,
- constants, function calls (e.g. sin,cos,log), and data file names in
- algebraic expressions. For example,
-
- PLOT(x*x-sin(x) / log(datafile+1) );
-
- Plot labels may be specified, text notes may be embedded in the plot,
- several different coordinate systems may be used (e.g. Log-Log or polar),
- and multiple traces may be generated on
- each plot. Hardcopies of plots may be output if your system has a printer
- that DAN supports.
-
- Data values to be processed can be:
- - Read from ASCII text files.
- - Read from files created by a user's application program, provided
- the file conforms to DAN's Data File format.
- - Generated from user specified formulas.
- - Entered directly from the keyboard by the operator.
- - Read from files previously output by DAN.
- - Input from any of the four analog or digital channels on a
- game controller.
- - Any combination of the above.
