function y=int1(z,n)
syms x n m z a;
for m=1:n;
z=int(z)

As I suggested earlier, you should really consider doing a basic Matlab tutorial. Have you already done that?

Why are you defining everything as symbolic? Why aren't you storing any output? Why are you overwriting your inputs with the syms function? The code below is one of the possible ways to answer these questions.

clc
clearvars
syms z
mySymFun= 3*z^2-9;
n=4;
y=int1(mySymFun,n);
clc,disp(y)
function z=int1(z,n)
%integrate z for n times
for m=1:n
    z=int(z);
end
end
