Class Sorgrq

    java.lang.Object
      org.netlib.lapack.Sorgrq

    public class Sorgrq

extends java.lang.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.

     *  Purpose
     *  =======
     *
     *  SORGRQ generates an M-by-N real matrix Q with orthonormal rows,
     *  which is defined as the last M rows of a product of K elementary
     *  reflectors of order N
     *
     *        Q  =  H(1) H(2) . . . H(k)
     *
     *  as returned by SGERQF.
     *
     *  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) REAL array, dimension (LDA,N)
     *          On entry, the (m-k+i)-th row must contain the vector which
     *          defines the elementary reflector H(i), for i = 1,2,...,k, as

     *          returned by SGERQF in the last 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) REAL array, dimension (K)
     *          TAU(i) must contain the scalar factor of the elementary
     *          reflector H(i), as returned by SGERQF.
     *
     *  WORK    (workspace/output) REAL array, dimension (MAX(1,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.
     *
     *          If LWORK = -1, then a workspace query is assumed; the routine
     *          only calculates the optimal size of the WORK array, returns
     *          this value as the first entry of the WORK array, and no error
     *          message related to LWORK is issued by XERBLA.
     *
     *  INFO    (output) INTEGER
     *          = 0:  successful exit
     *          < 0:  if INFO = -i, the i-th argument has an illegal value
     *
