图像处理于MATLAB上的应用，能很好的处理一些熵，概率等问题-(a)Find the entropy of this source using Matlab

(b)Design the Huffman code for this source using Matlab.

(c) Randomly generate a source sequence of length 500 symbols drawing the symbols from the true source distribution. Encode the generated sequence using the Huffman code developed in (b). Decode the sequence and compare the decoded and original sequences.

(d)Find the efficiency of the code in this case.
