CQRT13

CQRT13

Purpose:

!>
!> CQRT13 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

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

N

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

A

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

LDA

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

NORMA

!>          NORMA is REAL
!>          The one-norm of A.
!> 

ISEED

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