i want to draw a graph

i want to draw a graph on just command window.

f(x)=(exp(x).*sin(x)+(x./exp(x))

on 0<=x<=2*pi

but i got error! how i fix ?

>> f=@(x)(exp(x).*sin(x)+(x./exp(x))
x=linspace(0,2*pi,200);
error: parse error:

  anonymous function bodies must be single expressions

>>> x=linspace(0,2*pi,200);
    ^
>>

You are missing a close parenthesis

f=@(x)(exp(x).*sin(x)+(x./exp(x))
%     ^ no matching close parenthesis for this

That open parenthesis is not necessary, so you can remove it:

f=@(x)exp(x).*sin(x)+(x./exp(x))

or add a close parenthesis on the end of the line:

f=@(x)(exp(x).*sin(x)+(x./exp(x)))
