You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: pspm_sf_dcm.m
    path of file: ./repos/PsPM/src
    
    the code of the file until where you have to start completion: function varargout = pspm_sf_dcm(model, options)
% ● Description
%   pspm_sf_dcm does dynamic causal modelling for SF of the skin conductance
%   uses f_SF and g_Id
%   the input data is assumed to be in mcS, and sampling rate in Hz
% ● Format
%   function out = pspm_sf_dcm(model, options)
