Detailed Description
BLAS Level 2 API.
The gemv functions perform one of the matrix-vector operations:
y := alpha*A*x + beta*y, or y := alpha*A**T*x + beta*y, or y := alpha*A**H*x + beta*y,
where alpha and beta are scalars, x and y are vectors, and A is an m by n matrix.
- Parameters
-
[in] handle - [rocblas_handle] handle to the rocBLAS library context queue. [in] trans - [rocblas_operation] indicates whether matrix A is tranposed (conjugated) or not. [in] m - [rocblas_int] number of rows of matrix A. [in] n - [rocblas_int] number of columns of matrix A. [in] alpha - device pointer or host pointer to scalar alpha. [in] A - device pointer storing matrix A. [in] lda - [rocblas_int] specifies the leading dimension of A. [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.
