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.

• Supported precisions in rocBLAS : s, d, c, and z.
• Supported precisions in cuBLAS : s, d, c, and z.

Parameters

[in]	handle	- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]	trans	- [hipblasOperation_t] indicates whether matrix A is tranposed (conjugated) or not.
[in]	m	- [int] number of rows of matrix A.
[in]	n	- [int] number of columns of matrix A.
[in]	alpha	- device pointer or host pointer to scalar alpha.
[in]	AP	- device pointer storing matrix A.
[in]	lda	- [int] specifies the leading dimension of A.
[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.
