+/* ======= */
+
+/* SORMHR overwrites the general real M-by-N matrix C with */
+
+/* SIDE = 'L' SIDE = 'R' */
+/* TRANS = 'N': Q * C C * Q */
+/* TRANS = 'T': Q**T * C C * Q**T */
+
+/* where Q is a real orthogonal matrix of order nq, with nq = m if */
+/* SIDE = 'L' and nq = n if SIDE = 'R'. Q is defined as the product of */
+/* IHI-ILO elementary reflectors, as returned by SGEHRD: */
+
+/* Q = H(ilo) H(ilo+1) . . . H(ihi-1). */
+
+/* Arguments */
+/* ========= */
+
+/* SIDE (input) CHARACTER*1 */
+/* = 'L': apply Q or Q**T from the Left; */
+/* = 'R': apply Q or Q**T from the Right. */
+
+/* TRANS (input) CHARACTER*1 */
+/* = 'N': No transpose, apply Q; */
+/* = 'T': Transpose, apply Q**T. */
+
+/* M (input) INTEGER */
+/* The number of rows of the matrix C. M >= 0. */
+
+/* N (input) INTEGER */
+/* The number of columns of the matrix C. N >= 0. */
+
+/* ILO (input) INTEGER */
+/* IHI (input) INTEGER */
+/* ILO and IHI must have the same values as in the previous call */
+/* of SGEHRD. Q is equal to the unit matrix except in the */
+/* submatrix Q(ilo+1:ihi,ilo+1:ihi). */
+/* If SIDE = 'L', then 1 <= ILO <= IHI <= M, if M > 0, and */

+/* The leading dimension of the array C. LDC >= max(1,M). */
