Tengo mi codigo asi
Quiero evaluar esta funcion "sign(cos(2*pi*x))"
funcion =@(x) eval(app.FxEditField.Value);
f = funcion;
maxn = app.HarmonicsSpinner.Value;
xmin = str2double(app.StartEditField.Value);
xmax = str2double(app.EndEditField.Value);
x = linspace(xmin, xmax, 100);
y = polyval(f,x);
plot(app.UIAxes,x,y);
app.UIAxes.XLim = [xmin, xmax];

y = f(x);
This should work.
Esto debería funcionar (Spanish from Google Translate)
