DQRT13
DQRT13 generates a full-rank matrix that may be scaled to have large or small norm.
[in] | SCALE | SCALE is INTEGER SCALE = 1: normally scaled matrix SCALE = 2: matrix scaled up SCALE = 3: matrix scaled down |
[in] | M | M is INTEGER The number of rows of the matrix A. |
[in] | N | N is INTEGER The number of columns of A. |
[out] | A | A is DOUBLE PRECISION array, dimension (LDA,N) The M-by-N matrix A. |
[in] | LDA | LDA is INTEGER The leading dimension of the array A. |
[out] | NORMA | NORMA is DOUBLE PRECISION The one-norm of A. |
[in,out] | ISEED | ISEED is integer array, dimension (4) Seed for random number generator |
