**NAME**

LAPACK-3 - performs a very simple matrix-matrix multiplication

**SYNOPSIS**

SUBROUTINE ZLARCM( M, N, A, LDA, B, LDB, C, LDC, RWORK ) INTEGER LDA, LDB, LDC, M, N DOUBLE PRECISION A( LDA, * ), RWORK( * ) COMPLEX*16 B( LDB, * ), C( LDC, * )

**PURPOSE**

ZLARCM 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) DOUBLE PRECISION 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) DOUBLE PRECISION 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*16 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) DOUBLE PRECISION array, dimension (2*M*N) LAPACK auxiliary routine (version 3.2) April 2011 ZLARCM(3lapack)
