The exp2 model exists in the Curve Fitting Toolbox and is defined as:

```exp2     Y = a*exp(b*x)+c*exp(d*x)
```

Is that what you are referring to?

``` x=100%
res=exp(x)^2```

%or

` res=exp(x*2)`

exp^2(100) don't work. use exp(100)^2 or exp(2*100)

if so then exp^2(100) mean exp(2*100) or exp(100)^2 or (exp(100))^2

yes in theory, but in matlab coding : exp^2(100) is false
