How to plug in values from for loop to a single formula?

Hey guys, I was wondering, how would I input 3 variables that have multiple values into one equation in matlab? I ran my variables through a for loop so they have multiple values for each point and I have stored my values from each of the for loops into a single variable x. For example:

When x=1, y=2, z=3

When x=2, y=3, z=4

When x=3, y=4, z=5

Formula: x^2+y^2+z^2

I'm assuming you want the result for each set of inputs. Personally, I think the easiest way to do this is by putting the equation within the loop and indexing the results. Alternatively, I believe the following will work outside of the loop:

x = [1;2;3];
y = [2;3;4];
z = [3;4;5];
answer = x.^2+y.^2+z.^2;

The .^ symbols will cause each element of the x, y, and z arrays to be squared, rather than trying to square the entire matrix. Then, with all matrix math, addition applies straight across. Your answer then should be a 3x1 array of [14; 29; 50].
