Detailed Description

BLAS Level 2 API.

The hemv functions perform one of the matrix-vector operations:

y := alpha*A*x + beta*y

where alpha and beta are scalars, x and y are n -element vectors, and A is an n by n Hermitian matrix.

• Supported precisions in rocBLAS : c and z.
• Supported precisions in cuBLAS : c and z.

Parameters

[in]	handle	- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]	uplo	- [hipblasFillMode_t] HIPBLAS_FILL_MODE_UPPER: the upper triangular part of the Hermitian matrix A is supplied. HIPBLAS_FILL_MODE_LOWER: the lower triangular part of the Hermitian matrix A is supplied.
[in]	n	- [int] the order of the matrix A.
[in]	alpha	- device pointer or host pointer to scalar alpha.
[in]	AP	- device pointer storing matrix A. Of dimension (lda, n). if uplo == HIPBLAS_FILL_MODE_UPPER: The upper triangular part of A must contain the upper triangular part of a Hermitian matrix. The lower triangular part of A will not be referenced. if uplo == HIPBLAS_FILL_MODE_LOWER: The lower triangular part of A must contain the lower triangular part of a Hermitian matrix. The upper triangular part of A will not be referenced. As a Hermitian matrix, the imaginary part of the main diagonal of A will not be referenced and is assumed to be == 0.
[in]	lda	- [int] specifies the leading dimension of A. Must be >= max(1, n).
[in]	x	- device pointer storing vector x.
[in]	incx	- [int] specifies the increment for the elements of x.
[in]	beta	- device pointer or host pointer to scalar beta.
[in,out]	y	- device pointer storing vector y.
[in]	incy	- [int] specifies the increment for the elements of y.
