NAME

zlacrm - perform a very simple matrix-matrix multiplication

SUBROUTINE ZLACRM(
M, N, A, LDA, B, LDB, C, LDC, RWORK )

void zlacrm(long int m, long int n, doublecomplex ∗za, long int lda,
double ∗db, long int ldb, doublecomplex ∗zc, long int ldc)

INTEGER LDA, LDB, LDC, M, N

DOUBLE PRECISION B( LDB, ∗ ), RWORK( ∗ )

COMPLEX∗16 A( LDA, ∗ ), C( LDC, ∗ )

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.

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)
