GERC - General matrix rank 1 operation

pyclblas.clblasCgerc(order, M, N, alpha, X, offx, incx, Y, offy, incy, A, offa, lda, commandQueues, eventWaitList)

wraps: clblasCgerc

vector-vector product with float complex elements and performs the rank 1 operation A Vector-vector products:

  • ( A ← α X YH+ A )
Parameters:
  • order (clblasOrder [in]) – Row/column order.
  • M (int [in]) – Number of rows in matrix A.
  • N (int [in]) – Number of columns in matrix A.
  • alpha (complex [in]) – specifies the scalar alpha.
  • 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. On exit, A is overwritten by the updated matrix.
  • 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 when the order parameter is set to clblasRowMajor, or less than M when the parameter is set to clblasColumnMajor.
  • 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.
