?lacrm

Multiplies a complex matrix by a square real matrix.

Syntax

call clacrm( m, n, a, lda, b, ldb, c, ldc, rwork )

call zlacrm( m, n, a, lda, b, ldb, c, ldc, rwork )

Include Files

The FORTRAN 77 interfaces are specified in the mkl_lapack.fi include file (to be used in Fortran programs) and in the mkl_lapack.h include file (to be used in C programs).

Description

The routine performs a simple matrix-matrix multiplication of the form

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.

Input Parameters

m

INTEGER. The number of rows of the matrix A and of the matrix C (m ≥ 0).

n

INTEGER. The number of columns and rows of the matrix B and the number of columns of the matrix C

(n ≥ 0).
