TESTING/LIN/cqrt12.f(3) Library Functions Manual TESTING/LIN/cqrt12.f(3) NAME TESTING/LIN/cqrt12.f SYNOPSIS Functions/Subroutines real function cqrt12 (m, n, a, lda, s, work, lwork, rwork) CQRT12 Function/Subroutine Documentation real function cqrt12 (integer m, integer n, complex, dimension( lda, * ) a, integer lda, real, dimension( * ) s, complex, dimension( lwork ) work, integer lwork, real, dimension( * ) rwork) CQRT12 Purpose: CQRT12 computes the singular values `svlues' of the upper trapezoid of A(1:M,1:N) and returns the ratio || svlues -s ||/( ||s||*eps*max(M,N) ) Parameters M M is INTEGER The number of rows of the matrix A. N N is INTEGER The number of columns of the matrix A. A A is COMPLEX array, dimension (LDA,N) The M-by-N matrix A. Only the upper trapezoid is referenced. LDA LDA is INTEGER The leading dimension of the array A. S S is REAL array, dimension (min(M,N)) The singular values of the matrix A. WORK WORK is COMPLEX array, dimension (LWORK) LWORK LWORK is INTEGER The length of the array WORK. LWORK >= M*N + 2*min(M,N) + max(M,N). RWORK RWORK is REAL array, dimension (4*min(M,N)) Author Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd. Definition at line 95 of file cqrt12.f.
