public class Dorglq

extends Object

Following is the description from the original
Fortran source.  For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.
Contact seymour@cs.utk.edu with any questions.

 *     ..
 *
 *  Purpose
 *  =======
 *
 *  DORGLQ generates an M-by-N real matrix Q with orthonormal rows,
 *  which is defined as the first M rows of a product of K elementary
 *  reflectors of order N
 *
 *        Q  =  H(k) . . . H(2) H(1)
 *
 *  as returned by DGELQF.
 *
 *  Arguments
 *  =========
 *
 *  M       (input) INTEGER
 *          The number of rows of the matrix Q. M >= 0.
 *
 *  N       (input) INTEGER
 *          The number of columns of the matrix Q. N >= M.
 *
 *  K       (input) INTEGER
 *          The number of elementary reflectors whose product defines the
 *          matrix Q. M >= K >= 0.
 *
 *  A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
 *          On entry, the i-th row must contain the vector which defines
 *          the elementary reflector H(i), for i = 1,2,...,k, as returned
 *          by DGELQF in the first k rows of its array argument A.
 *          On exit, the M-by-N matrix Q.
 *
 *  LDA     (input) INTEGER
 *          The first dimension of the array A. LDA >= max(1,M).
 *
 *  TAU     (input) DOUBLE PRECISION array, dimension (K)
 *          TAU(i) must contain the scalar factor of the elementary
 *          reflector H(i), as returned by DGELQF.
 *
 *  WORK    (workspace/output) DOUBLE PRECISION array, dimension (LWORK)
 *          On exit, if INFO = 0, WORK(1) returns the optimal LWORK.
 *
 *  LWORK   (input) INTEGER
 *          The dimension of the array WORK. LWORK >= max(1,M).
 *          For optimum performance LWORK >= M*NB, where NB is
 *          the optimal blocksize.
 *
 *  INFO    (output) INTEGER
 *          = 0:  successful exit
 *          < 0:  if INFO = -i, the i-th argument has an illegal value
 *
