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	[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]	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	[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
