| SUBROUTINE F_ZAXPY_DOT ( N, ALPHA, W, INCW, V, INCV, U, INCU ) | |
Input | N | Number of elements of vector. |
| ALPHA | The scalar ALPHA. |
| W | REAL or COMPLEX array, minimum length |
|
| (N - 1) x incw + 1. |
| INCW | Increment for the array w. A vector w having |
|
| component wi, i = 1,...,n, is stored in an array |
|
| W() with increment argument incw. If incw > 0 then wi |
|
| is stored in W (1 + (i - 1) x incw). If incw < 0 then wi is |
|
| stored in W(1 + (N - i) x incw). |
incw = 0 is an illegal value.
