Parameters:
  • order (clblasOrder [in]) – Row/column order.
  • uplo (clblasUplo [in]) – The triangle in matrix being referenced.
  • trans (clblasTranspose [in]) – How matrix A is to be transposed.
  • diag (clblasDiag [in]) – Specify whether matrix A is unit triangular.
  • N (int [in]) – Number of rows/columns in matrix A.
  • A (pyopencl.Buffer [in]) – Buffer object storing matrix in packed format. A.
  • offa (int [in]) – Offset in number of elements for first element in matrix A.
  • X (pyopencl.Buffer [out]) – Buffer object storing vector X.
  • offx (int [in]) – Offset in number of elements for first element 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:
