How to write a program to take mode of vector without using built in function 'mode'?

We are using Matlab. We cannot develop an algorithm and need very descriptive and specific steps as to how to solve our question.

Smells like homework to me :-)

Can you use the built-in function hist()? If you can, this is trivially easy:

If you are not permitted to use matlab's 'mode' function, and if your vector is a column vector called v, do this:

 s = sort(v);
 [~,p] = max(diff(find([true;diff(s)~=0;true])));
 md = s(p); % <-- This is the most frequent value in v
