Max vector find without function max

Question

I have problem with finding max number in vector without max function, I know that I can use max but without that?

Normally I will do that B = max(X) , I dont know how to limit end , because I use X(i+1) and I can't find more numbers that are not in the vector.

X = [0 1 1 2 3 3 3 5]

My bad solution how to start?

for i = 1:length(X) - 1

if X(i) < X(i+1)

else X(i) > X(length(X+1))

end

So I'm not clear why you don't want to use the max function, but alright! Here's a solution:

X = [0 1 1 2 3 3 3 5]
currMax = -inf;
for i = 1:length(X)
    if X(i) > currMax;currMax = X(i); end;
end
disp(currMax);

"... I'm not clear why you don't want to use the max function ..."

Because this is obviously homework.

Fair point, I don't love just solving people's homework
