Detailed Description

BLAS Level 2 API.

hemv performs 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.

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]alphadevice pointer or host pointer to scalar alpha.
[in]Adevice 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]xdevice pointer storing vector x.
[in]incx[int] specifies the increment for the elements of x.
[in]betadevice pointer or host pointer to scalar beta.
[in,out]ydevice pointer storing vector y.
[in]incy[int] specifies the increment for the elements of y.
