Make the Huffman-tree from the lengths of the Huffman codes. The Huffman codes are also needed, and if they are known, they can be given as an extra input argument.

光学实验模拟，主要针对干涉，衍射实验，以及正弦、余弦光栅生成的MATLAB程序。(Simulation of optical experiments, mainly for interference, diffraction experiments, as well as sine, cosine grating generated MATLAB program.)

切比雪夫插值（利用切比雪夫点进行多项式插值），对连续函数进行逼近。(Chebyshev interpolation (using Chebyshev polynomial interpolation points), for continuous function approximation)
