资料中包含波达方向估计的一种常用方法，包括一维MUSIC和二维MUSIC，可以有效的估计出多个信号方向。(A common method of data contained in the DOA estimates, including one-dimensional and two-dimensional MUSIC MUSIC, can effectively estimate multiple signal direction.)

现代谱估计的程序，对给定的随机信号利用yule-walker方程进行谱估计与其理想功率谱进行谱估计的对比，并比较参数。(Modern spectral estimation procedures, given the use of yule-walker random signal spectrum estimation equation from its ideal power spectrum spectrum estimation contrast and compare the parameters.)

BP算法，异或和认证，本人数据挖掘小作业(BP algorithm, XOR and certification, data mining operations)

说明：  matlab课程大作业，共两个小程序，一个是根据shouming.txt 中的数据分析人均寿命分布情况；另一个是任意输入两个相向而行的波的幅度、频率、相位，观察这两个波叠加的动画，比如可以形成驻波、拍等典型的波(matlab course great job, a total of two small programs, one is based on shouming.txt life expectancy in the distribution of data analysis the other is the two meet each other halfway arbitrary input wave amplitude, frequency, phase, observation of these two waves superposition of the animation, such as to form a standing wave, making the typical wave)
