DFT Computation

ComputeForward computes the forward DFT.
Fortran:
Status = DftiComputeForward (Desc_Handle, X_inout)
Status = DftiComputeForward (Desc_Handle, X_in, X_out)
Status = DftiComputeForward (Desc_Handle, X_inout, Y_inout)
Status = DftiComputeForward (Desc_Handle, X_in, Y_in, X_out, Y_out)
C:
status = DftiComputeForward (desc_handle, x_inout);
status = DftiComputeForward (desc_handle, x_in, x_out);
status = DftiComputeForward (desc_handle, x_inout, y_inout);
status = DftiComputeForward (desc_handle, x_in, y_in, x_out, y_out);

ComputeBackward computes the backward DFT.
Fortran:
Status = DftiComputeBackward (Desc_Handle, X_inout)
Status = DftiComputeBackward (Desc_Handle, X_in, X_out)
Status = DftiComputeBackrward (Desc_Handle, X_inout, Y_inout)
Status = DftiComputeBackward (Desc_Handle, X_in, Y_in, X_out, Y_out)
C:
status = DftiComputeBackward (desc_handle, x_inout);
status = DftiComputeBackward (desc_handle, x_in, x_out);
status = DftiComputeBackward (desc_handle, x_inout, y_inout);
status = DftiComputeBackward (desc_handle, x_in, y_in, x_out, y_out);
