Huffman coding with frequencies

hey everyone , i am new to matlab and i want to implement huffman coding algorithm in which input will be symbols and frequencies , also frequencies must not be between 0-1 ,can be any positive integer. I found some functions like

[dist avgvalue] = huffmandict(symbols,p);

but it takes only probability vector that must be 0 to 1 also the sum of all probabilities should be 1 here, but in my case p can be any positive integer. example:

symbol    frequencies
  1         3
  2          9
 11          10 
 0           0

and so on

please provide some help thanks in advance

the experimental probability for any given symbol is the frequency for it divided by the total of the frequencies.
