That code give me an Error like
Error using symfun>validateArgNames (line 333)
Second argument must be a scalar or vector of unique
symbolic variables.
Error in symfun (line 78)
y.vars = validateArgNames(inputs);
Error in coba_ae (line 7)
y =symfun( x + exp(x), x);

Hi Ahmed, almost there:
syms x y
y = symfun(x + exp(x),x);
figure(1)
fplot(y,[-13,13])
grid on
In your code you declare x to be a nummeric vector, however, to create the symbolic function y it needs to be a symbolic variable.
