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)))
