matlab_utilities/initializeController.cpp

MEX file that initializes a fuzzy Controller from a fuzzy Plant.

MATLAB help:

% INITIALIZECONTROLLER Initializes a fuzzy Controller from a fuzzy Plant.
% 
%   Controller = initializeController(Plant)
% 
% Arguments:
% 
%   Plant -> Plant model. This model could be a '.txt' file, a '.fis' file,
%            or a 'FIS' variable from MATLAB Workspace.
%
%   Controller -> An initial controller based in the Plant. This controller
%                 has all its consecuents to 0, and each of its outputs have
%                 so many rules as all of the plant.
