## Re: Need Help Plotting exp(-0.5*x)*sin(x)

```You are using vector and exp(x)*sin(x) it does not what you see.

[exp(x1), exp(x2), ........ exp(xn)] * [sin(x1) , sin(x2) .........
sin(xn) ]

what kind of product do you what to apply ? It does not make sense unless you
transpose the second matrix
and you get a scalar product of the vectors.

To multiply memer by member use .

exp(x).*sin(x) = [exp(x1)*sin(x1), exp(x2)*sin(x2), .........]
