Write out by hand a MATLAB script for finding the maximum value within an array, A. Assume the array is given and you can calculate the size of the array using the MATLAB command size. You cannot use any other MATLAB built-in functions, including max.
I don't even know how to start this process. Not asking for the assignment to be done for me. Just some tips or hints. Thanks

It’s been a very long while since I wrote in assembler, but if I remember correctly, even machine code has relational and conditional operators. Barring all of them at any level makes this assignment absolutely impossible.

Relational operators such as < or <= and others might be useful. Since you’re allowed to use size, read the documentation on for and if as well.

I finally got it. And I used
a=(blah)
[m,n]= size(a)
For I=1:1:m
For j=1:1:n
If blah
. X=max
. Else stuff
And went from there. It's too hard to respond from my phone. But thanks for the correct answer!. And yes we do a lot of code by hand. It has been helpful.
