F_SSUM/F_DSUM/F_CSUM/F_ZSUM | Sum of entries of a vector | |
| X | REAL or COMPLEX array, minimum length |
|
| (N - 1) x incx + 1. |
| 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 xi is 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. |
Output | R | REAL scalar. The sum of the entries of vector x. |
