Visualization of Huffman Encoding Trees

Simple program that builds and visualizes a huffman encoding tree for a user-defined string

This program demonstrates how Huffman Encoding works by performing huffman encoding on a user-defined string. The program builds the huffman tree based on user-input and builds a complete huffman tree and code book using built-in MATLAB functions.

A user can edit the string to encode by editing the value of "my_str". The user also has the ability to calculate character probabilities manually or automatically based on ASCII values by changing the "auto_prob" flag and the "prob_dist" variables.
