If I have a vector with say, 10 elements, such as vec = [11 23 34 60 58 65 55 42 35 21], is there a way to find the maximum value between specified locations within the vector? For example, I want to find the location between locations 1 and 5 that has the maximum value. So, the answer would be 4.

You need to use the second (optional) return value of the max() function. That tells you the index where the maximum occurs . And of course just put starting and stopping indexes inside vec when you pass it to max() if you don't want it to examine the entire vector.
vec = [11 23 34 60 58 65 55 42 35 21]
[maxValue, indexOfMax] = max(vec(1:5)) % Find max in first 5 elements.
