说明：  自己写的一个计算空间时频分布的程序，可知指定Cohen类分布类型WVD，CWD，PWVD，SPWVD，BJD(himself in a room when calculating the frequency distribution procedures, we can see Cohen category designated distribution type WVD, CWD, Wigner, SPWVD, BJD etc.)

用matlab实现的RS码编码与解码器，实现了15，11RS码的编解码仿真，并编写了测试驱动，直观明确(Matlab implementation of RS codes with encoding and decoding devices to achieve 15,11 RS code decoding simulation, and the preparation of the test-driven, intuitive, clear)

对模拟信号抽样，然后进行离散傅里叶变换，利用自编DFT函数，得到频谱，然后进行频谱的还原。(Sampling the analog signal, then the discrete Fourier transform, DFT self function obtained spectrum and the spectrum reduction.)

这是关于电力系统潮流计算的若干源程序，基于MATLAB开发，仅供参考(This is the power flow calculation of power system on a number of source code, based on the MATLAB development, for reference only)

做经验模态分解用的几个有用函数,真的非常有用。(Do empirical mode decomposition several useful function is really useful.)

This is the region growing segmentation algrithm for gray image, user must add a seed point.

说明：  Matlab的 各种插值法..代码，Lagrange插值..Newton插值... Hermite插值... 分段低次插值... 三次样条插值 二维插值...(Various interpolation methods of MATLAB.)

说明：  这是为想学习Matlab的学习者准备的足够练习题，实例子，有了它们，你可以很好的去练习而不是纸上谈兵。(This is to prepare learners want to learn enough Matlab exercises, case children, with them, you' re good to practice rather than on paper.)
