noise cancellation program

对灰度图像进行拉普拉斯算子锐化，提取灰度图像的边缘。(Laplace operator sharpening, extract the edge of the gray image gray image.)

The median filtering algorithm on matlab

说明：  按FPE定阶的 源程序：fpe.cpp M序列：M序列.txt 白噪声：Gauss.txt 程序中先用依模型阶次递推算法估计模型的参数，再用fpe方法判断模型的阶次。 程序运行结果如下： n: 1 判断阶次FPE的值: 0.0096406 -0.481665 1.07868 n: 2 判断阶次FPE的值: 0.00875755 -0.446739 0.00498181 1.07791 0.0527289 n: 3 判断阶次FPE的值: 0.0087098 -0.459433 0.120972 -0.0569228 1.07814 0.0390757 0.116982 n: 4 判断阶次FPE的值: 0.000396884 -0.509677 0.4501 -0.200906 0.0656188 1.07991 -0.0156362 0.442989 0.0497236 n: 5 判断阶次FPE的值: 3.2095e-007 -1.18415 0.813123 -0.517862 0.34881 -0.116864 1.07999 -0.744141 0.474462 -0.253112 0.122771 n: 6 判断阶次FPE的值: 3.23349e-007 -1.14659 0.76933 -0.487651 0.329676 -0.10377 -0.00440907 1.07999 -0.703574 0.447253 -0.235282 0.113587 0.00479688 从以上结果可以看出，当n=5时，fpe值最小，所以这时的模型阶次和参数估计值为最优结果： 3.2095e-007 -1.18415 0.813123 -0.517862 0.34881 -0.116864 1.07999 -0.744141 0.474462 -0.253112 0.122771(err)

一个小的matlab程序利用RBFNN进行函数拟合(A small matlab program using RBFNN for function fitting)

说明：   这个函数可以产生阶越函数并且可以多次调用产生矩形函数(This function can generate the more function-order and can be multiple calls to generate the rectangular function)

Kernel Principal Conponent Analysis 特征提取(Kernel Principal Conponent Analysis feature extraction)

基于有限元的矩形短边双脊波导的传输特性matlab代码包括衰减系数，单模带宽，截止波长功率容量等(Based on the short side of the rectangular finite element double-ridged waveguide transmission characteristics include attenuation coefficient matlab code, single-mode bandwidth cutoff wavelength power capacity, etc.)

一个基于Simulink及GUIDE的PID控制界面呢DEMO.用户可以从面板上修改PID参数，直接仿真出PID结果(A demo application using simulink &GUIDE to accomlish PID control.Users can modify KP,KI,KD from the GUI for their own desired simulation conditions.)

说明：  一个MATLAB的应用程序，很方便的！使用时需要转换为M文件。(a MATLAB applications, a convenient! Use need to change for the M documents.)
