TESTING/MATGEN/zlarge.f

SYNOPSIS

  Functions/Subroutines
subroutine zlarge (n, a, lda, iseed, work, info)
ZLARGE

Function/Subroutine Documentation

  subroutine zlarge (integer n, complex*16, dimension( lda, * ) a, integer lda, integer, dimension( 4 ) iseed, complex*16, dimension( * ) work, integer info)

ZLARGE

Purpose:

    !>
    !> ZLARGE pre- and post-multiplies a complex general n by n matrix A
    !> with a random unitary matrix: A = U*D*U'.
    !>

Parameters
    N

    !>          N is INTEGER
    !>          The order of the matrix A.  N >= 0.
    !>

    A

    !>          A is COMPLEX*16 array, dimension (LDA,N)
    !>          On entry, the original n by n matrix A.
    !>          On exit, A is overwritten by U*A*U' for some random
    !>          unitary matrix U.
    !>

    LDA

    !>          LDA is INTEGER
    !>          The leading dimension of the array A.  LDA >= N.
    !>

    ISEED

    !>          ISEED is INTEGER array, dimension (4)
    !>          On entry, the seed of the random number generator; the array
    !>          elements must be between 0 and 4095, and ISEED(4) must be
    !>          odd.
    !>          On exit, the seed is updated.
    !>

    WORK

    !>          WORK is COMPLEX*16 array, dimension (2*N)
    !>

    INFO

    !>          INFO is INTEGER
    !>          = 0: successful exit
    !>          < 0: if INFO = -i, the i-th argument had an illegal value
    !>
