Description
This function performs the matrix-vector multiplication : y = Ξ± * op(A)x + Ξ² * y
Type : polymorphic.
Input parameters
Β A : class, 2D tensor of dimension N x M.Β x : class, 1D tensor of dimension M.Β y : class, 1D tensor of dimension N. The default is an N-element vector with all elements equal to 0.
Op(A) : enum, operation that is non- or transpose.
-
- CUBLAS_OP_N : the non-transpose operation is selected
- CUBLAS_OP_T : the transpose operation is selected
- CUBLAS_OP_H : the conjugate transpose operation is selected
Ξ±Β : float, scalar used for multiplication. Ξ²Β : float, scalar used for multiplication, if beta==0 then y does not have to be a valid input.
Output parameters
Β y : class, 1D tensor of dimension N.
