DQRT13

Purpose:



 DQRT13 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 DOUBLE PRECISION 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
