/*          = 'U':      Upper triangular part */

/*          Otherwise:  All of the matrix A */

/*  M       (input) INTEGER */
/*          The number of rows of the matrix A.  M >= 0. */

/*  N       (input) INTEGER */
/*          The number of columns of the matrix A.  N >= 0. */

/*  A       (input) COMPLEX array, dimension (LDA,N) */
/*          The m by n matrix A.  If UPLO = 'U', only the upper trapezium */
/*          is accessed; if UPLO = 'L', only the lower trapezium is */
/*          accessed. */

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