MATLAB: How to fetch the column numbers in a vector

Question

Ok so I have vector v v= [0 1 0 2 6 2] through the operation c = numel(find(v==2)) I can find how many times the number 2 is repeated.

However, how can I make matlab tell me the column numbers where the 2 is repeated?

Could someone tell me please? I appreciate it greatly.

Answer 1

Just use find:

columns = find(v==2);
