NAME

ZLACRM - perform a very simple matrix-matrix multiplication

SYNOPSIS

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

PURPOSE

ZLACRM 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*16 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) DOUBLE PRECISION 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*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,N).
RWORK (workspace) DOUBLE PRECISION array, dimension (2*M*N)
