"Function" function doesn't work

when I write function dx, this appears. Error: Function definition are not supported in this context. Functions can only be

created as local or nested functions in code files. How can i solve this problem?

Maybe you have a function after your script in an m-file. If so, add and "end" line after the last line of your function.

function results = dx()
% Body of the function.....
end  % Add this line.
