Hi all

I have made a loop which outputs a number of numbers.  Ie e=123 or e=125.  I would like to count the frequency of the numbers.  How would I do this.

Thanks

Hi
Convert number to string and get the length of string
e.g
x=1234;
length(num2str(x))

%if you mean by "a number of numbers" an array like
  X = [123 125 11 123 123 12 125]
% you can count them using
  unX = unique(X)
  freq = histc(X,unX)
  disp([unX(:) freq(:)])
