- Explanation of the contents of ~4Dgifts/toolbox/libs
- ----------------------------------------------------
-
- The following libraries and software are provided exclusively
- for use on Silicon Graphics computers.
-
- Copyright (c) 1991, 1992, 1993, Silicon Graphics, Inc.
- All Rights Reserved.
-
- The math libraries included herein have been updated to Irix 5.1.
- Everything has been recompiled and tested. Different versions
- have been added for mips1 and mips2, serial and parallel. The
- BLAS .a file's have been pulled out since they are available with
- the Irix 5.1 compilers.
-
- This subtree contains four different math library groupings:
-
-
- -- blas:
- test programs, a demo and the original source code for
- the BLAS (Basic Linear Algebra Subprograms);
- optimized and parallelized versions of the BLAS for IRIS
- workstations can be found in:
- /usr/lib/libblas.a
- /usr/lib/libblas_mp.a
- /usr/lib/mips2/libblas.a
- /usr/lib/mips2/libblas_mp.a
- for details about the different versions consult the manpage
- for blas or the README file in the blas directory;
-
- -- libconv:
- an optimized library featuring Convolutions for Finite
- Impulse Response (FIR) and Infinite Impulse Response
- (IIR) filters, together with correlations. The library
- modules take 1D and 2D inputs and are available in
- single and double precision for real and complex
- arithmetic. The 2D subroutines have been parallelized
- and take full advantage of SGI's parallel architecture.
-
- -- libfft:
- written by Jean-Pierre Panziera at SGI, libfft is a
- library of utilities for performing Fast Fourier
- Transforms (FFT), including one, two and three
- dimensional FFT's. LIBFFT uses a "row-column"
- algorithm based on 1D FFT's from FFTPACK;
-
- -- psort:
- written by Jean-Pierre Panziera at SGI, psort is a
- parallel implementation of the Merge-Sort algorithm
- optimized for IRIS workstations. The "psort" calling
- sequence is the same as for the C library "qsort"
- routine;
-
- -- skyline:
- contains the SKYLIB library, skylib.a. SKYLIB is a
- library of Fortran 77 routines for solving linear
- systems of equations where the matrix is banded, with
- the bands varying in width, and stored in a packed form
- known as skyline.
-

- For more information, please consult the various README
- files under each of these four subtrees.
