NAME¶

CLARCM - performs 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, * )

PURPOSE¶

CLARCM 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).

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,M).

RWORK (workspace) REAL array, dimension (2*M*N)
