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]uplorocblas_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]alphaspecifies the scalar alpha
[in]Apointer storing matrix A on the GPU
[in]xpointer storing vector x on the GPU
[in]incx[rocblas_int] specifies the increment for the elements of x
[in]betaspecifies the scalar beta
[out]ypointer storing vector y on the GPU
[in]incy[rocblas_int] specifies the increment for the elements of y
