lacrm - lacrm: complex * real matrix-matrix multiply

SYNOPSIS

Functions


subroutine CLACRM (m, n, a, lda, b, ldb, c, ldc, rwork)
CLACRM multiplies a complex matrix by a square real matrix. subroutine ZLACRM (m, n, a, lda, b, ldb, c, ldc, rwork)
ZLACRM multiplies a complex matrix by a square real matrix.

Detailed Description

Function Documentation

subroutine CLACRM (integer m, integer n, complex, dimension( lda, * ) a, integer lda, real, dimension( ldb, * ) b, integer ldb, complex, dimension( ldc, * ) c, integer ldc, real, dimension( * ) rwork)

CLACRM multiplies a complex matrix by a square real matrix.

Purpose:

!>
!> CLACRM 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.
!>

Parameters

M 

!>          M is INTEGER
!>          The number of rows of the matrix A and of the matrix C.
!>          M >= 0.
!>

N

!>          N is INTEGER
!>          The number of columns and rows of the matrix B and
!>          the number of columns of the matrix C.
!>          N >= 0.
!>

A

!>          A is COMPLEX array, dimension (LDA, N)
!>          On entry, A contains the M by N matrix A.
!>

LDA

!>          LDA is INTEGER
!>          The leading dimension of the array A. LDA >=max(1,M).
!>

B

!>          B is REAL array, dimension (LDB, N)
!>          On entry, B contains the N by N matrix B.
!>

LDB

!>          LDB is INTEGER
!>          The leading dimension of the array B. LDB >=max(1,N).
!>

C

!>          C is COMPLEX array, dimension (LDC, N)
!>          On exit, C contains the M by N matrix C.
!>

LDC

!>          LDC is INTEGER
!>          The leading dimension of the array C. LDC >=max(1,N).
!>

RWORK

!>          RWORK is REAL array, dimension (2*M*N)
!>
