clblasCsyrk
(order, uplo, transA, N, K, alpha, A, offA, lda, beta, C, offC, ldc, commandQueues, eventWaitList)¶ wraps: clblasCsyrk
Rankk update of a symmetric matrix with complex float elements. Extended version. Rankk updates:
 ( C ← α A A^{T}+ β C )
 ( C ← α A^{T}A + β C )
where C is a symmetric matrix.Parameters:  order (clblasOrder [in]) – Row/column order.
 uplo (clblasUplo [in]) – The triangle in matrix C being referenced.
 transA (clblasTranspose [in]) – How matrix A is to be transposed.
 N (int [in]) – Number of rows and columns in matrix C.
 K (int [in]) – Number of columns of the matrix A if it is not transposed, and number of rows otherwise.
 alpha (complex [in]) – The factor of matrix A.
 A (pyopencl.Buffer [in]) – Buffer object storing the 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.
 beta (complex [in]) – The factor of the matrix C.
 C (pyopencl.Buffer [out]) – Buffer object storing matrix C.
 offC (int [in]) – Offset of the first element of the matrix C in the buffer object. Counted in elements.
 ldc (int [in]) – Leading dimension of matrix C. 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.
