zlacrm: performs a very simple matrix-matrix multiplication

NAME

ZLACRM - performs 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)
