clblasDsymv
(order, uplo, N, alpha, A, offA, lda, x, offx, incx, beta, y, offy, incy, commandQueues, eventWaitList)¶ wraps: clblasDsymv
Matrixvector product with a symmetric matrix and double 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 A.
 alpha (float [in]) – The factor of matrix A.
 A (pyopencl.Buffer [in]) – Buffer object storing matrix A.
 offA (int [in]) – Offset of the first element of the matrix A in the buffer object. Counted in elements.
 lda (int [in]) – Leading dimension of matrix A. It cannot less than N.
 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 (float [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.
