not formed from a valid identifier; using the end function for a simple m file.

I am essentially copying the exact same code my prof used on powerpoint and yet the code keeps telling me this doesnt work. No matter what I put for the last line an error says " is not formed from a valid matlab identifier.

a=e^2 
if a<x     
disp ('a is less than x'); 
elseif a>x     
disp ('a is greater than x'); 
end

[EDITED, Jan, code formatted]

note each of those functions are on different lines!

@Kyle: Please use the "{} Code" button to format code. Thanks.

If you post the complete error message, the readers do not have to guess in which line it appears.

Please note that e and x are not predefined variables in MATLAB. If you want e to be the base of the natural logarithms then you would need to define it to be that,

e = exp(1)

e^2 in MATLAB would be written as exp(2)
