%In your workspace do this
MyVariable=diff('x^2');

%In your GUI do this
MyVariable = evalin('base', 'MyVariable');

%MyVariable will be a symbolic expression, if you want it in string format
MyVariable=char(MyVariable) %convert it to a string
%Converts to string but also inserts a . before any ^, * or / in s
%MyVariable=vectorize(MyVariable)
