Opens a dialog box to define a Laplace transfer function. This is used to interface to the simulator devices s_xfer and Laplace.
The former implements a Laplace transfer function using a network of integrators while the latter uses frequency-time domain conversion by convolution.
This dialog box provides a unified user interface to both devices.

Returns
Return type: string array
The function returns a string array of length 14 with the same format as the argument
described above. If the user selects "Cancel" the function returns an empty vector.
