pyclblas.
clblasCscal
(N, alpha, X, offx, incx, commandQueues, eventWaitList)¶ wraps: clblasCscal
Scales a complex-float vector by a complex-float constant.
- ( X ← α X )
Parameters: - N (int [in]) – Number of elements in vector X.
- alpha (complex [in]) – The constant factor for vector X.
- X (pyopencl.Buffer [out]) – 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 X. Must not 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.

Scales a double vector by a double constant.
- ( X ← α X )
Parameters: - N (int [in]) – Number of elements in vector X.

- incx (int [in]) – Increment for the elements of X. Must not 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.
