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

/* The number of columns and rows of the matrix B and */
/* the number of columns of the matrix C. */
/* N >= 0. */
/* A (input) COMPLEX*16 array, dimension (LDA, N) */
/* A contains the M by N matrix A. */
