NAME
     CLACRM - perform a very simple matrix-matrix multiplication

SYNOPSIS
     SUBROUTINE CLACRM( M, N, A, LDA, B, LDB, C, LDC, RWORK )

         INTEGER        LDA, LDB, LDC, M, N

         REAL           B( LDB, * ), RWORK( * )

         COMPLEX        A( LDA, * ), C( LDC, * )

IMPLEMENTATION
     These routines are part of the SCSL Scientific Library and can be loaded
     using either the -lscs or the -lscs_mp option.  The -lscs_mp option
     directs the linker to use the multi-processor version of the library.

     When linking to SCSL with -lscs or -lscs_mp, the default integer size is
     4 bytes (32 bits). Another version of SCSL is available in which integers
     are 8 bytes (64 bits).  This version allows the user access to larger
     memory sizes and helps when porting legacy Cray codes.  It can be loaded
     by using the -lscs_i8 option or the -lscs_i8_mp option. A program may use
     only one of the two versions; 4-byte integer and 8-byte integer library
     calls cannot be mixed.

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.


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) COMPLEX array, dimension (LDA, N)
             A contains the M by N matrix A.

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

     B       (input) REAL array, dimension (LDB, N)
             B contains the N by N matrix B.

     LDB     (input) INTEGER
             The leading dimension of the array B. LDB >=max(1,N).
     C       (input) COMPLEX 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,N).

     RWORK   (workspace) REAL array, dimension (2*M*N)
