Detailed Description

BLAS Level 2 API.

The spmv functions perform 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.

• Supported precisions in rocBLAS : s and d.
• Supported precisions in cuBLAS : s and d.

Parameters

[in]	handle	- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]	uplo	- [hipblasFillMode_t] specifies either 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]	alpha	specifies the scalar alpha.
[in]	AP	- pointer storing matrix A on the GPU.
[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.
