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.

Parameters
[in]handle- [rocblas_handle] handle to the rocBLAS library context queue.
[in]uplo- [rocblas_fill]
  • rocblas_fill_upper: the upper triangular part of the Hermitian matrix A is supplied.
  • rocblas_fill_lower: the lower triangular part of the Hermitian matrix A is supplied.
[in]n- [rocblas_int] the order of the matrix A.
[in]alpha- device pointer or host pointer to scalar alpha.
[in]A- device pointer storing matrix A. Of dimension (lda, n). 
if uplo == rocblas_fill_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 == rocblas_fill_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- [rocblas_int] specifies the leading dimension of A. Must be >= max(1, n).
[in]x- device pointer storing vector x.
[in]incx- [rocblas_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- [rocblas_int] specifies the increment for the elements of y.
