clblasChpmv
(order, uplo, N, alpha, AP, offa, X, offx, incx, beta, Y, offy, incy, commandQueues, eventWaitList)¶ wraps: clblasChpmv
Matrixvector product with a packed hermitian matrix and floatcomplex elements. Matrixvector products:
 ( Y ← α A X + β Y )
Parameters:  order (clblasOrder [in]) – Row/columns order.
 uplo (clblasUplo [in]) – The triangle in matrix being referenced.
 N (int [in]) – Number of rows and columns in matrix AP.
 alpha (complex [in]) – The factor of matrix AP.
 AP (pyopencl.Buffer [in]) – Buffer object storing packed matrix AP.
 offa (int [in]) – Offset in number of elements for first element in matrix AP.
 X (pyopencl.Buffer [in]) – Buffer object storing vector X.
 offx (int [in]) – Offset of first element of vector X in buffer object. Counted in elements.
 incx (int [in]) – Increment for the elements of vector X. It cannot be zero.
 beta (complex [in]) – The factor of vector Y.
 Y (pyopencl.Buffer [out]) – Buffer object storing vector Y.
 offy (int [in]) – Offset of first element of vector Y in buffer object. Counted in elements.
 incy (int [in]) – Increment for the elements of vector Y. It cannot be zero.
 commandQueues (pyopencl.CommandQueue [in]) – OpenCL command queues. A list, tuple, or single instance of pyopencl.CommandQueue. Must not be None.
 eventWaitList (pyopencl.Event [in]) – Event wait list. A list, tuple, or single instance of pyopencl.Event. May be None.
Returns: A tuple of pyopencl.Event instances, one for each commandQueue supplied.
