clblasCtrsv
(order, uplo, trans, diag, N, A, offa, lda, X, offx, incx, commandQueues, eventWaitList)¶ wraps: clblasCtrsv
solving triangular matrix problems with floatcomplex elements. Matrixvector products:
 ( A X ← X )
 ( A^{T}X ← X )
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 A.
 offa (int [in]) – Offset in number of elements for first element in matrix A.
 lda (int [in]) – Leading dimension of matrix A. It cannot be less than N.
 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: A tuple of pyopencl.Event instances, one for each commandQueue supplied.
