Well, the for loop begins with i=0 which pretty clearly is a problem...

You'll need to arrange for the array to start at E(1) as Matlab doesn't
use (or allow) 0-based arrays.

Old code:

syms x;
for i=0:24
E(i)=int(((0.09)*x^(2)*exp(-0.3*x)/factorial(2)),i,i+1);
end

Revised code:

syms x;
for i=1:25
E(i)=int(((0.09)*x^(2)*exp(-0.3*x)/factorial(2)),i-1,i);
end
