| Z | REAL or COMPLEX array, minimum length | |
|
| (N - 1) x incz + 1. |
|
| INCZ | Increment for the array y. A vector z having component | |
|
| zi, i = 1,..., n, is stored in an array Z() with increment | |
|
| argument incw. If incw > 0 then zi is stored in | |
|
| Z(1 + (i - 1) x incw). If incw < 0 then ziis stored in | |
|
| Z(1 + (N - i) x incw). incw = 0 is an illegal value. | |
