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.
