Detailed Description
BLAS Level 2 API.
sbmv performs the matrix-vector operation:
y := alpha*A*x + beta*y,
where alpha and beta are scalars, x and y are n element vectors and A should contain an upper or lower triangular n by n symmetric banded matrix.
- Parameters
-
[in] handle [hipblasHandle_t] handle to the hipblas library context queue. [in] uplo [hipblasFillMode_t] specifies whether the upper 'HIPBLAS_FILL_MODE_UPPER' or lower 'HIPBLAS_FILL_MODE_LOWER' if HIPBLAS_FILL_MODE_UPPER, the lower part of A is not referenced if HIPBLAS_FILL_MODE_LOWER, the upper part of A is not referenced [in] n [int] [in] k [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 [int] specifies the leading dimension of matrix A [in] x pointer storing vector x on the GPU [in] incx [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 [int] specifies the increment for the elements of y
