F_SNORM/F_DNORM |
| Norm of a vector |
Input | NORM | Specifies the norm to compute. Seven distinct values |
|
| are possible, namely the |
|
| |
|
| matrices, the |
|
| |
|
| matrices. Use one of the following constants: |
|
| BLAS_ONE_NORM BLAS_REAL_ONE_NORM |
|
| BLAS_INF_NORM BLAS_REAL_INF_NORM |
|
| BLAS_TWO_NORM BLAS_FROBENIUS_NORM |
|
| BLAS_MAX_NORM BLAS_REAL_MAX_NORM |
|
| When you specify NORM = BLAS_FROBENIUS_NORM, |
|
| an error flag is not raised, and the routine returns the |
|
| |
| N | Number of elements of vector x. |
| X | REAL array, minimum length |
| INCX | Increment for the array x. A vector x having component |
|
| xi, i = 1,..., n, is stored in an array X() with increment |
|
| argument incx. If incx > 0 then xiis stored in |
|
| X (1 + (i - 1) x incx). If incx < 0 then xi is stored in |
|
| X (1 + (N - i) x incx). incx = 0 is an illegal value. |
