function zero_middle(h)
[n,m]=size(h);
for ii=1:n;
for jj=1:m;
if mod(ii,2) && mod(jj,2);
h(end/2+1/2)=0;
end
end
end
end

You are trying to run your code by pressing the green Run button . You need to go down to the command line and invoke the code instead . Like
mm = magic(9);
zm = zero_middle(mm);

function h= zero_middle(h)
h(end/2+1/2,end/2+1/2)=0;
end
