With what code can I make Matlab do this operation automatically

Good morning.
I hope you can help me.
How can I enter the elements of a vectror automatically in the formula, to obtain the value of E and then introduce the elements of the next vector. Everything automatically.

x2=[2 4 6 8 1 3 5 2 3 1]
x3=[2 1 4 2 6 4 8 3 8 3]
E=exp(x1(1))+exp(x1(2))+exp(x1(3))+exp(x1(4))+exp(x1(5))+exp(x1(6))+exp(x1(7))+exp(x1(8))+exp(x1(9))+exp(x1(10))

First thanks for answering. I have E1 is evaluated with the vector A0, now it is necessary to evaluate with the vector A1 and A2. Evaluate A0, A1 and A2 automatically. Thanks and regards

Try this:
E = sum(exp(x1))
E =
34.8438
You can also create an anonymous function to do this:
Efcn = @(x) sum(exp(x));
E = Efcn(x1)
and use it as you would any other function.

To do all of them at once:
x1=[1 2 3 4 5 6 7 8 9 10];
x2=[2 4 6 8 1 3 5 2 3 1];
x3=[2 1 4 2 6 4 8 3 8 3];
E = sum(arrayfun(@exp, [x1; x2; x3]), 2)
E =
34.8438
3.6478
6.5322
