CLARCM(3S)CLARCM(3S)NAMECLARCM - perform a very simple matrix-matrix multiplication
SYNOPSIS
SUBROUTINE CLARCM( M, N, A, LDA, B, LDB, C, LDC, RWORK )
INTEGER LDA, LDB, LDC, M, N
REAL A( LDA, * ), RWORK( * )
COMPLEX B( LDB, * ), 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.
PURPOSECLARCM performs a very simple matrix-matrix multiplication: C :=
A * B,
where A is M by M and real; B is M by N and complex;
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) REAL array, dimension (LDA, M)
A contains the M by M 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 M by N matrix B.
LDB (input) INTEGER
The leading dimension of the array B. LDB >=max(1,M).
