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: std_limodesign.m
    path of file: ./repos/eeglab/functions/studyfunc
    
    the code of the file until where you have to start completion: % STD_LIMODESIGN - create LIMO design matrices for categorical and 
%                    continuous variables.
%
% Usage:
%   >> [catMat,contMat,description] = std_limosavedesignfiles(factors, trialinfo)
%   >> [catMat,contMat,description] = std_limosavedesignfiles(factors, trialinfo, 'key', val)
%
% Inputs:
%   factors      - [struct] list of factors (structure containing fields
%                  'label' [string], 'value' [string or int] and 'vartype'
%                  ('categorical' or 
    
function POP_LISTFACTORS.
%   trialinfo    - [struct] trial information structure as returned by
%                  STD_COMBTRIALINFO.
%
% Optional inputs:
%   filepath     - [string] file path. If not empty, categorical_variables.txt
%                  and continuous_variables.txt files are saved.
%   'splitreg'   - ['on'|'off'] split regression for different categorical
%                  factors. Default is 'off'.
%   'interaction' - ['on'|'off'] compute interaction when using different
%                  categorical variables. This allows computing interactions
%                  between all variables - NOT the same as 'full factorial'
%                  Default is 'off'.
%   'desconly'    - ['on'|'off'] only output description
%
%  Outputs:
%    catMat      - [array] design matrix for categorical variables
%    contMat     - [array] design matrix for continuous variables
%    description - [cell] what each columns contains
