C++绘图代码，绘制矩形，圆，三角形，直线，折线等较简单的平面图形-C++ drawing code to draw a rectangle, circle, triangle, straight lines, polylines, and other relatively simple plane figure

这是使用Matlab实现的Huffman编码与绘图的程序。编码过程比较简单，是通过建立Huffman树，再进行简单的遍历得到。 主要贡献在绘图部分。这是迄今为止唯一一个画出Huffman生成树的Matlab程序。-This is a piece of Huffman coding and graphics program based on matlab. The encoding process is relatively simple, through the establishment of
