SRC/DEPRECATED/dgelqs.f(3) Library Functions Manual NAME SRC/DEPRECATED/dgelqs.f SYNOPSIS Functions/Subroutines subroutine dgelqs (m, n, nrhs, a, lda, tau, b, ldb, work, lwork, info) DGELQS Function/Subroutine Documentation subroutine dgelqs (integer m, integer n, integer nrhs, double precision, dimension( lda, * ) a, integer lda, double precision, dimension( * ) tau, double precision, dimension( ldb, * ) b, integer ldb, double precision, dimension( lwork ) work, integer lwork, integer info) DGELQS Purpose: Compute a minimum-norm solution min || A*X - B || using the LQ factorization A = L*Q computed by DGELQF. Parameters M M is INTEGER The number of rows of the matrix A. M >= 0. N N is INTEGER The number of columns of the matrix A. N >= M >= 0. NRHS NRHS is INTEGER The number of columns of B. NRHS >= 0. A A is DOUBLE PRECISION array, dimension (LDA,N) Details of the LQ factorization of the original matrix A as returned by DGELQF. LDA LDA is INTEGER The leading dimension of the array A. LDA >= M. TAU TAU is DOUBLE PRECISION array, dimension (M) Details of the orthogonal matrix Q. B B is DOUBLE PRECISION array, dimension (LDB,NRHS) On entry, the m-by-nrhs right hand side matrix B. On exit, the n-by-nrhs solution matrix X. LDB LDB is INTEGER The leading dimension of the array B. LDB >= N. WORK WORK is DOUBLE PRECISION array, dimension (LWORK) LWORK LWORK is INTEGER The length of the array WORK. LWORK must be at least NRHS, and should be at least NRHS*NB, where NB is the block size for this environment. INFO INFO is INTEGER = 0: successful exit < 0: if INFO = -i, the i-th argument had an illegal value Author Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
