说明：  计算100的阶乘的具体数字 关于数学计算 位运算(the actual result for 100!)

说明：  matlab的bp神经网络算法以及准确率的计算，训练函数采用lm算法(Matlab bp neural network algorithm and accuracy calculation, training function using LM algorithm)

matlab的netcdf插件安装程序，适用于R14版本(Matlab netcdf plug-in installation procedures, apply to R14 version )

基于matlab的LMS、LMS牛顿算法。用于实现步长K改变对LMS、NLMS的影响。(LMS、NLMS methods based on Matlab. To test the changes when change the K.)

这是一维小波去噪程序 包括4种阈值和软硬阈值去噪，以及去噪后精度评定，方便大家一起学习(This is a one-dimensional wavelet denoising procedure Including four threshold and soft threshold denoising, and accuracy uation after denoising, facilitate everybody study together )

四模块永磁轮毂电机的容错控制策略的仿真，使用的是矢量控制的策略。(Permanent magnet synchronous motor using two-phase four-leg vector control simulation, on the basis of the platform can simulate the four-module permanent magnet wheel motor fault tolerance, including speed, torque ripple.)

小波去噪 用了几种不同的方式进行限制，有软域值，硬域值还有新开发的一种方式(wavelet)

Matlab_Simulink 无人机的控制和建模(Using matlab/simulink to control the unmanable aircraft )

说明：  image noise identification system.. when given a noisy image,program tells us the type of noise which is present in image

using the magic time-step in 1D FDTD grid, implement a total-field/scattered-field wave-source.
