霍夫曼信源编码，针对一串数据 进行霍夫曼压缩 得到霍夫曼树(Huffman coding)

The aim of this assignment is to use the Finite Difference Method to numerically determine the transverse electromagnetic (TEM) transmission line (TL) parameters of a line with a coupled ribbon shaped cross-section. To achieve this, a computer program was developed to perform the finite difference calculation the computer program used in this report was Matlab.
