/*  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) */
