So what I'm trying to do is have a function take in a vector of inputs, and then use them seperately in a function. So the function would be something simple, like adding 1 to every input value, but I want the limit of input values to be practically infinite. So I want to assign the variable x to every component of a vector and add 1 to each component, then at the end I want to obtain the sum of every component in the vector. I don't quite know how else to ask this question, something like
x = [1, 2, 3 . . . .]
answer = sum(x+1)

I figured it out, I had misplaced some of the '.' to specify that I was multiplying vectors. As well, I just needed to specify that I wanted the sum of the output. So sum(answer) to get it to all add up.

Most Matlab functions are vector based. you should use .^ for vector based ^ and .* for vector based *
So you function line looks like this:
answer = sum((x+1).^2 .* mod(x, 2));
and ./ instead of /
