Matlab code for for Fourier Transform

用于将长的信号break into小的piece，然后对每段小piece做信号处理，然后再将整个的信号还原回原始信号长度。(The signal is used to break into long small piece, and then each small piece to do signal processing, and then restore the signal back to the original signal length.)

MATLAB编程书籍，帮助加深对MATLAB的学习和程序应用(MATLAB programming books to help deepen the learning and procedures for application of MATLAB)

说明：  时间序列的自回归预测模型，是一个利用前期若干时刻的随机变量的线性组合来描述以后某时刻随机变量的线性回归模型(The autoregressive prediction model of time series is a linear regression model that describes random variables at a later time by using the linear combination of random variables at some earlier time.)

一些数学建模用到的函数，代码，初学者可以试着编译看输出结果(some function to make mathmatic model)

基于拉普拉斯光滑算子的变换，常用于人脸识别(Smooth operator based on Laplace transform, using face recognition program)

说明：  直角坐标潮流程序，极好的程序，可计算任意规模的潮流，不必改程序，只要修改数据即可(Rectangular current procedures, an excellent program, calculate the trend of any size, no need to change procedures, as long as you can modify the data)
