clblasCher2
(order, uplo, N, alpha, X, offx, incx, Y, offy, incy, A, offa, lda, commandQueues, eventWaitList)¶ wraps: clblasCher2
Hermitian rank 2 operation with a general triangular matrix and floatcompelx elements. Hermitian rank 2 operation:
 ( A ← α X Y^{H}+ conj{ α } Y X^{H}+ A )
Parameters:  order (clblasOrder [in]) – Row/column order.
 uplo (clblasUplo [in]) – The triangle in matrix being referenced.
 N (int [in]) – Number of columns in matrix A.
 alpha (complex [in]) – The factor of matrix A.
 X (pyopencl.Buffer [in]) – Buffer object storing vector X.
 offx (int [in]) – Offset in number of elements for the first element in vector X.
 incx (int [in]) – Increment for the elements of X. Must not be zero.
 Y (pyopencl.Buffer [in]) – Buffer object storing vector Y.
 offy (int [in]) – Offset in number of elements for the first element in vector Y.
 incy (int [in]) – Increment for the elements of Y. Must not be zero.
 A (pyopencl.Buffer [out]) – Buffer object storing matrix A.
 offa (int [in]) – Offset in number of elements for the first element in matrix A.
 lda (int [in]) – Leading dimension of matrix A. It cannot be less than N.
 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.
