PCA预测回归的一个例子，简单易懂 也有注释，导入数据注意格式即可使用(An example PCA regression forecasting, easy to understand but also notes, pay attention to the format to use to import data)

其中包含了两个用matlab编写的Zernike程序。(Which contains two Zernike prepared using matlab program.)

夏氏递推算法。利用附件中的数据进行运算，给出运行结果。这是我们最近课程中用到的一个例程，希望对大家有用。(xiashiditui. Use the data contained in the annex to the operations, given the operating results. This is a routine we have recently used in the course, the hope that useful.)

输入一个任意长的数字序列，使用幅度调制法调制，然后使用包络检波法解调(Enter an arbitrarily long sequence of numbers, use the modulation amplitude modulation method, and then use the envelope detection method demodulation)

读取matlab 文件夹中所有的文件路径 包括子文件夹的文件路径(Read all matlab folder including subfolders file path file path)

这个例子里，我们将独立(白噪声)样本通过有5dB通带纹波的切比雪夫滤波器。 试估计滤波器输出端的PSD。实现这一估计的MATLAB程序如下: (This example, we will be independent (white noise) samples through a 5dB passband ripple Chebyshev filter. Estimate the filter output PSD. MATLAB program to achieve this estimate is as follows:)
