NAME

/home/abuild/rpmbuild/BUILD/lapack-3.12.0/TESTING/MATGEN/clarge.f

SYNOPSIS

Functions/Subroutines


subroutine CLARGE (n, a, lda, iseed, work, info)
CLARGE

Function/Subroutine Documentation

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

CLARGE

Purpose:

!>
!> CLARGE 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 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 array, dimension (2*N)
!>

INFO

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