I have a vector, say "Voltage" and it's 400 elements long. I want to calculate the min and max every 100 indicies and store that in a vector. How can I do that? I was thinking a for loop would be what I want, but I don't know how to make the loop scan the entire Voltage vector and make the min and max calculations every 100 indicies. Would it be a nested loop?

I would use the movmax function and its friends, or if you want to calculate the maximum or minimum over 100-element blocks of your vector, use the reshape function. Note that reshape requires that your vector be an integer multiple of 100 elements, or that you truncate it to meet that criterion.
