Dica para trabalhar com variáveis no Simulink

2 Bloco com parâmetros

function parametros


persistent postloadFlag;
if isempty(postloadFlag)
    postloadFlag = true;
else
    if postloadFlag
        postloadFlag = false;ip
        return
    end
end

settingsBlock = [bdroot '/parametros'];
[symbol_rate] = getSettings(settingsBlock,'symbol_rate');
[M_ary] = getSettings(settingsBlock,'M_ary');


p.symbol_rate = symbol_rate;
p.M = M_ary;

 
%Assign variables to base workspace
 assignin('base', 'p', p);

function varargout = getSettings(settingsBlock, varargin)

 varargout = cell(size(varargin));

 h = get_param(settingsBlock, 'handle');
 for n = 1:length(varargin)
     varargout{n} = evalin('base', get(h, varargin{n}));
 end
