F_STRMV/F_DTRMV/F_CTRMV/F_ZTRMV | Triangular | |
| N | Number of rows and columns in matrix A, and |
|
| elements of vector X. n > 0. If n ≤ 0 , the subprograms |
|
| do not reference A or X. |
| ALPHA | The scalar ALPHA. |
| A | REAL or COMPLEX array, dimension (LDA, N). |
| LDA | Leading dimension of array A. If lda < 1 or lda < n, an |
|
| error condition is generated. |
| 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 xiis stored in |
|
| X (1 + (N - i) x incx). incx = 0 is an illegal value. |
Output | X | The updated X vector replaces the input. |
