轮轨冲击信号的小波分析matlab程序,程序中H5V20zrail为轮轨冲击信号输入数据。(Wheel-rail impact of wavelet analysis matlab program, the program H5V20zrail impact signal for the wheel-rail input data.)

地震信号处理，虚同相轴方法预测层间多次波，将数据分成上下两部分，利用相关和褶积的原理预测出层间多次波。预测信号和原始信号在相位和振幅上存在差异，用L1范数匹配法进行匹配，其中，提供了两种方法解病态方程，分别为高斯-赛德尔方法和正则化方法。(Seismic signal processing, predicte internal multiples by construct virtual events .The data is divided into two parts, using the principle of correlation and convolution to predicte multiples. There are differences between the prediction signal and the original signal on the phase and amplitude, so we use the L1 norm method to match the singal.We provide two methods for solving ill equation, respectively Gauss- Seidel method and regularization method.)

利用simulink和模糊工具箱建立模糊控制器，实现模糊控制，模糊PID控制，模型参考自适应控制等(The fuzzy controller is built by Simulink and fuzzy toolbox to realize fuzzy control, fuzzy PID control, model reference adaptive control and so on.)

该程序是MATLAB源程序，可以用来对纹理进行处理得到纹理特征。(MATLAB source code of the procedure can be used for processing of the texture to be texture features.)
