I skipped all of my lectures since I usually like to understand things on my own but I am regretting it for recursion. I don't know why but I am finding it quite unintuitive and confusing. I have an exam coming tomorrow so I have to make sure that I understand it correctly.(adsbygoogle = window.adsbygoogle || []).push({});

I know that recursion functions as a loop due to its circulatory nature. However, I don't know exactly what is going on within the program to make it loop around here. Can someone clarify?

Find largest number using recursion.

function output = maxrec(vec)

% finds the largest number in a vector recursively.

% base case, if the vector has a length of 1, reuturn the single element.

% if not, return the larger of the 2 numbers

if length(vec) == 1

output = vec;

else

current = maxrec(vec(1,1));

next = maxrec(vec(1, 2:1:length(vec)));

if current > next

output = current;

else

output = next;

end

end

end
