Ahn,

I think you are right. You need an individual decision of which branch of the
function to use for each element of x.

Try this:
function y=f(x)
flags1 = (x>1);
flags2 = (x<=1);
y = ones(rows(x), columns(x)) .* flags1 + x.^2 .* flags2 ;
endfunction
So you build complementary matrices of flags for your cases of x(i,j)>1 and
x(i,j)<=1 and then overlay the results.
