Say you have a function f(x) that you wish to integrate in steps from a to b.

Two ways of writing this program would be:

syms x;
i=1;
while i<=10
I=int(f(x),i-1,i)
i=i+1;
end

syms x;
for i=1:10
I=int(f(x),i-1,i)
end

Obviously the while loop is more code to write, but will it effect the efficiency of the program? I'm thinking that the while loop is going to take more time to compute, can anyone confirm this? What's the advantages of using a while loop in a situation like this, if any?
