pzplot in symbolic toolbox

Hi, I'm using following command to achieve tf of Y_out.

   for l=1:4
    [symNum,symDen] = numden(Y_out(1,l)); %Get num and den of Symbolic TF
    TFnum = sym2poly(symNum);    %Convert Symbolic num to polynomial
    TFden = sym2poly(symDen);    %Convert Symbolic den to polynomial
    sys =tf(TFnum,TFden);
    pzplot(sys)
   end

as you can see Y_out has 1 row and 4 column.

how can I PZPLOT the sys(1),...,sys(4) all in a same plot or different plots?

thx

‘as you can see Y_out has 1 row and 4 column.’

We cannot see any of that because they are not provided.

This could work, although I cannot even test it or simulate it because I do not know what ‘Y_out’ is:

   for l=1:4
    [symNum,symDen] = numden(Y_out(1,l)); %Get num and den of Symbolic TF
    TFnum = sym2poly(symNum);    %Convert Symbolic num to polynomial
    TFden = sym2poly(symDen);    %Convert Symbolic den to polynomial
    sys =tf(TFnum,TFden);
    figure
    pzplot(sys)
   end
