|
| incy | Increment for the array y, incy ≠ 0: | |
|
| incy > 0 | y is stored forward in array y; that is, |
|
|
| yi is stored in y((i−1)⋅incy+1). |
|
| incy < 0 | y is stored backward in array y; that |
|
|
| is, yi is stored in y((i−n)⋅incy+1). |
|
| Use incy = 1 if the vector y is stored contiguously in | |
|
| array y, that is, if yi is stored in y(i). Refer to “BLAS | |
|
| Indexing Conventions” in the introduction to | |
|
| Chapter 2. |
|
| a | Array containing the | |
| lda | The leading dimension of array a as declared in the | |
|
| calling program unit, with lda ≥ max(m,1). | |
Output | a | The updated A matrix replaces the input. | |
