As shipped in IRIX 6.5.15. Added in IRIX 6.5.15.
NAME CLACRM - perform a very simple matrix-matrix multiplication SYNOPSIS SUBROUTINE CLACRM( M, N, A, LDA, B, LDB, C, LDC, RWORK ) INTEGER LDA, LDB, LDC, M, N REAL B( LDB, * ), RWORK( * ) COMPLEX A( LDA, * ), C( LDC, * ) IMPLEMENTATION These routines are part of the SCSL Scientific Library and can be loaded using either the -lscs or the -lscs_mp option. The -lscs_mp option directs the linker to use the multi-processor version of the library. When linking to SCSL with -lscs or -lscs_mp, the default integer size is 4 bytes (32 bits). Another version of SCSL is available in which integers are 8 bytes (64 bits). This version allows the user access to larger memory sizes and helps when porting legacy Cray codes. It can be loaded by using the -lscs_i8 option or the -lscs_i8_mp option. A program may use only one of the two versions; 4-byte integer and 8-byte integer library calls cannot be mixed. PURPOSE CLACRM performs a very simple matrix-matrix multiplication: C := A * B, where A is M by N and complex; B is N by N and real; C is M by N and complex. ARGUMENTS M (input) INTEGER The number of rows of the matrix A and of the matrix C. M >= 0. N (input) INTEGER The number of columns and rows of the matrix B and the number of columns of the matrix C. N >= 0. A (input) COMPLEX array, dimension (LDA, N) A contains the M by N matrix A. LDA (input) INTEGER The leading dimension of the array A. LDA >=max(1,M). B (input) REAL array, dimension (LDB, N) B contains the N by N matrix B. LDB (input) INTEGER The leading dimension of the array B. LDB >=max(1,N). C (input) COMPLEX array, dimension (LDC, N) C contains the M by N matrix C. LDC (input) INTEGER The leading dimension of the array C. LDC >=max(1,N). RWORK (workspace) REAL array, dimension (2*M*N) SEE ALSO INTRO_LAPACK(3S), INTRO_SCSL(3S) This man page is available only online.
