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.
