Would you please help me plot the function x^2 between [-2,2]?
This does not work, and would you please explain why that does not work? I think that fplot does not accept x^2 but why?
>> fplot(@(x^2)x, [-1,1]
fplot(@(x^2)x, [-1,1]
↑
Error: Unexpected MATLAB operator.
Thank you.

Your syntax is wrong
fplot(@(x) x.^2, [-1,1])
