function [y,yz]=my_conv(x1,x2,z1,z2)
%output zero
yz=-(-z1+1-z2+1)+1;
%output length
ylen=length(x1)+length(x2)-1;
y=zeros(ylen);
x11=[x1,zeros(length(x2))];
x22=[x2,zeros(length(x1))];
for i=1:ylen
    for j=1:i
            y(i)=y(i)+x11(j)*x22(i-j+1);
    end
end
end

is there anything wrong with my function?

Did you try running it yourself? Then you will ge the same error.

You could check the edits Chien made in his answer.
