ZQRT13

Purpose:

!>
!> ZQRT13 generates a full-rank matrix that may be scaled to have large
!> or small norm.
!>

Parameters

SCALE

!>          SCALE is INTEGER
!>          SCALE = 1: normally scaled matrix
!>          SCALE = 2: matrix scaled up
!>          SCALE = 3: matrix scaled down
!>

!>          M is INTEGER
!>          The number of rows of the matrix A.
!>

!>          N is INTEGER
!>          The number of columns of A.
!>

!>          A is COMPLEX*16 array, dimension (LDA,N)
!>          The M-by-N matrix A.
!>

LDA

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

NORMA

!>          NORMA is DOUBLE PRECISION
!>          The one-norm of A.
!>

ISEED

!>          ISEED is integer array, dimension (4)
!>          Seed for random number generator
!>
