.. py:function:: create_operator(identifier, domain, range_, dual_to_range, parameters, assembler, operator_options, kernel_type, assembly_type, device_interface, precision, is_complex)

   Create a generic operator.


.. py:function:: create_multitrace_operator(identifier, domain, range_, dual_to_range, parameters, assembler, operator_options, multitrace_kernel, singular_contribution, device_interface, precision)

   Create a generic operator.


.. py:function:: pade_coeffs(order, angle)

   Calculate the coefficients of the Pade series expansion of the square root.

   Parameters
   ----------
   order : int
       The order of the expansion.

       The coefficients of the Pade expansion of the square root.


.. py:function:: inv_sqrt_pade_coeffs(order, angle=_np.pi / 3)

   Calculate the coefficients of the Pade series expansion of the inverse square root.

   Parameters
   ----------
   order : int
       The order of the expansion.
   angle : float
       The branch-cut angle of the expansion (pi/3 is recommended).

   Returns
