MEX file that extracts data from antecedent of a fuzzy model.
MATLAB help:
% ANTEC2MAT Extracts data from antecedent of a fuzzy model.
%
% Vector = antec2mat(Fuzzy_Model)
%
% Vector = antec2mat(Fuzzy_Model,Output,Rule)
%
% [Vector, length] = antec2mat(Fuzzy_Model)
%
% [Vector, length] = antec2mat(Fuzzy_Model,Output,Rule)
%
% Arguments:
%
% Vector -> Vector with data from fuzzy model antecedent.
%
% Output -> Use to select the antecedent of one output.
%
% Rule -> Use to select the antecedent of one rule for the given output.
%
% length -> The length of Vector, 0 if error.
%
% Fuzzy_Model -> This fuzzy model could be a '.txt' file, a '.fis' file,
% or a 'FIS' variable from MATLAB Workspace.
