Find the cumulative maximum of an array without using the built-in function cummax (and a few others). Your function should act identically to cummax, allowing the same inputs.
Examples
If X = [0 4 3
6 5 2]
cumax(X,1) is [0 4 3 and cumax(X,2) is [0 4 4
6 5 3] 6 6 6]
cumax(X,1,'reverse') is [6 5 3 and cumax(X,2,'reverse') is [4 4 3
6 5 2] 6 5 2]
Also,
cumax([8 9 1 10 6 1 3 6 10 10]) returns [8 9 9 10 10 10 10 10 10 10]
cumax([8 9 1 10 6 1 3 6 10 10]') returns [8 9 9 10 10 10 10 10 10 10]'

There is a problem is the first test.
Remove the assert(isempty(strfind(filetext,'max'))) because the name of the function cumax contains the string max.
Thank you.
@Matthew, could you be so kind and fix the first test? As it is, it is impossible to solve this problem since the function name "cumax" itself contains the string "max".
This also makes it impossible to obtain the Matrix Manipulation III badge.
