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)
