The library complib.sgimath is installed on the SGI's and can be invoked from C and Fortran programs. It contains an extensive collection of industry standard libraries such as Basic Linear Algebra Subprograms (BLAS), the Extended BLAS (Level 2 and Level 3), EISPACK, LINPACK, and LAPACK. Internally developed libraries for calculating Fast Fourier Transforms (FFT's) and Convolutions are also included, as well as select direct sparse matrix solvers. Documentation is available per routine via individual man pages. General man pages for complib ( man complib ), the Blas ( man blas ), fft routines ( man fft ), convolution routines ( man conv ) and LAPACK ( man lapack ) are also available on our SGI's.
