Imagine this Example:

A = {'Steve';'wonder';'Marcus';'Jacob'};

and i want to convert to

B =['1-Steve 2-wonder 3-marcus 4-Jacob'];

I'm doing that inside of an loop!

What is the best way to solve that? Thanks

A = {'Steve';'wonder';'Marcus';'Jacob'};
B = strjoin(strcat(cellstr(num2str((1:numel(A)).')),'-',A).','  ')

13a or newer for strjoin

A loop is fine for something like that.

The problem is I have hundreds of cells and each one has a different length and I want to put numbers like showed above.

Your problem is not a problem. Even if you have 5000 cells, it will still be pretty fast.
