lacrm - lacrm: complex * real matrix-matrix multiply


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.

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)
