NAME

ZLARCM - 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 := 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)
