Detailed Description
BLAS Level 2 API.
spmv 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 packed symmetric matrix.
- Parameters
-
[in] handle [rocblas_handle] handle to the rocblas library context queue. [in] uplo rocblas_fill specifies whether the 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] alpha specifies the scalar alpha [in] A pointer storing matrix A on the GPU [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
