Finding max, min or avg value of a section of vector

I have a vector of size 35116x1. I want to find max, min or avg of only a section of the vector like only using the first 2926 elements. I tried using index but it doesn't work. Am I doing anything wrong here or is there any other way of doing it?

for i=1:2926
  max(num2(i,1))         %num2 is the vector
end

if your vector num2 includes the first 2926 elements:

max(num2);

min(num2);

mean(num2);

Otherwise use you can use:

max(yourVector(1:2926))

That works. Thank you!

subset = num2(1:2926);
max(subset)
min(subset)
mean(subset)

When finding the minimum of the subset, is there a way to eliminate zeroes in the subset? Thanks.

nonzeros(subset)

That works. Thanks!
