I need to convert an integer into a string with 4 digits; I mean if the number is 4, I need "0004", if the number is 360, I need "0360", and so on. The string function doesn't work for this. I would like to do it without using the if statement. Thank you.

You can use sprintf
s=sprintf('%05d',124);
disp(s);
%05d means that you have leading zeros and the total length 0f 5
