+/*  ======= */
+
+/*  SLATRZ factors the M-by-(M+L) real upper trapezoidal matrix */
+/*  [ A1 A2 ] = [ A(1:M,1:M) A(1:M,N-L+1:N) ] as ( R  0 ) * Z, by means */
+/*  of orthogonal transformations.  Z is an (M+L)-by-(M+L) orthogonal */
+/*  matrix and, R and A1 are M-by-M upper triangular matrices. */
+
+/*  Arguments */
+/*  ========= */
+
+/*  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. */
+
+/*  L       (input) INTEGER */
+/*          The number of columns of the matrix A containing the */
+/*          meaningful part of the Householder vectors. N-M >= L >= 0. */
+
+/*  A       (input/output) REAL array, dimension (LDA,N) */
+/*          On entry, the leading M-by-N upper trapezoidal part of the */
+/*          array A must contain the matrix to be factorized. */
+/*          On exit, the leading M-by-M upper triangular part of A */
+/*          contains the upper triangular matrix R, and elements N-L+1 to */
+/*          N of the first M rows of A, with the array TAU, represent the */
+/*          orthogonal matrix Z as a product of M elementary reflectors. */
+
+/*  LDA     (input) INTEGER */
+/*          The leading dimension of the array A.  LDA >= max(1,M). */

+/*  TAU     (output) REAL array, dimension (M) */
+/*          The scalar factors of the elementary reflectors. */

+/*    A. Petitet, Computer Science Dept., Univ. of Tenn., Knoxville, USA */
+
+/*  The factorization is obtained by Householder's method.  The kth */
+/*  transformation matrix, Z( k ), which is used to introduce zeros into */
+/*  the ( m - k + 1 )th row of A, is given in the form */

+/*     Z( k ) = ( I     0   ), */

+/*  tau is a scalar and z( k ) is an l element vector. tau and z( k ) */
+/*  are chosen to annihilate the elements of the kth row of A2. */
+
+/*  The scalar tau is returned in the kth element of TAU and the vector */
+/*  u( k ) in the kth row of A2, such that the elements of z( k ) are */
+/*  in  a( k, l + 1 ), ..., a( k, n ). The elements of R are returned in */
