Else if Question with function

??

Write a program to evaluate the function f (x, y) for any two values x and y, where the function f (x, y) is defined as follows; f (x, y) = x+y if x and y are greater than or equal to 0, f (x, y) = x+y^2 if x is greater than or equal to 0 and y is less than 0, f (x, y) = x^2+y if x is less than 0 and y is greater than or equal to 0 and f (x, y) = x^2+y^2 if x and y are less than 0.

Check

function
if
elseif

To start with

function op = f(x,y)
if (x>=0 && y>=0)
op=x+y;
elseif(x>=0 && ... 
....%If you want to deserve your marks, you should fill this up!
....
end

edited output to op.

This is my final code, but it comes up as incorrect? Am I making a mistake somewhere?

function output = f(x,y)
if (x>=0 && y>=0)
op=x+y;
elseif(x>=0 && y<0)
op=x+y^2;
elseif(x<0 && y>=0)
op=x^2+y;
elseif(x<0 && y<0)
op=x^2+y^2;
end

You assign to a variable op but do not do anything with it afterwards.

You do not assign to the output variable output so it would not be possible to call the function in a context that used the output.
