Detailed Description
BLAS Level 2 API.
The sbmv functions perform the matrix-vector operation:
y := alpha*A*x + beta*y
where alpha and beta are scalars, and x and y are n-element vectors. A should contain an upper or lower triangular n by nsymmetric banded matrix.
- Parameters
-
[in] handle - [rocblas_handle] handle to the rocBLAS library context queue. [in] uplo - [rocblas_fill] specifies either upper (rocblas_fill_upper) or lower (rocblas_fill_lower). - if rocblas_fill_upper, the lower part of A is not referenced.
- if rocblas_fill_lower, the upper part of A is not referenced.
[in] n - [rocblas_int] [in] k - [rocblas_int] specifies the number of sub- and super-diagonals. [in] alpha specifies the scalar alpha. [in] A - pointer storing matrix A on the GPU. [in] lda - [rocblas_int] specifies the leading dimension of matrix A. [in] x - pointer storing vector x on the GPU. [in] incx - [rocblas_int] specifies the increment for the elements of x. [in] beta - specifies the scalar beta. [out] y - pointer storing vector y on the GPU. [in] incy - [rocblas_int] specifies the increment for the elements of y.
