Description

This function performs the matrix-vector multiplication : y = α * op(A)x + β * y
Type : polymorphic.

Input parameters

 A : class, 2D tensor of dimension N x M.
 x : class, 1D tensor of dimension M.
 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

α : float, scalar used for multiplication.
β : float, scalar used for multiplication, if beta==0 then y does not have to be a valid input.

Output parameters

 y : class, 1D tensor of dimension N.
