Please post your code as code (see here for a GIF showing how to do it).

What are you stuck on? Doesn't this work? What error are you getting? If you don't know how to use fprintf have you read its documentation?

Also note that you made a small typo:

if x>=0
    if y>=0 % you have y>0

For reference, one way to do this in matlab without any if at all, in just one line:

fun = x.^(1 + (x<0)) + y.^(1 + (y<0))

I was considering this approach as well. The middle ground between these would be to make it compatible with array inputs by using x(n) in a for-loop.

The above is compatible with array inputs, as long as x and y are of compatible size.
