对于特征维数降维的matlab工具箱，包括PCA LDA　ＰＰＣＡ　等(Matlab Toolbox for Dimensionality Reduction (v0.7.1- June 2010) )

用MATLAB编写与仿真了MSK信号，其中结合了自己写的快速傅立叶变换实现了MSK信号的调制还有解调，而且作为拓展，还加入噪声、通过带通滤波器、低通滤波器、载波信号等等。调制解调都很有用，画出的图也很漂亮规范。(Using MATLAB and the simulation of the MSK signal, which combines the fast Fourier transform to write their own modulation there demodulation of MSK signals, but also as a development, but also by adding noise, band-pass filter, low pass filter, the carrier signaland so on. The modem is very useful to draw the plan is also very beautiful and specification.)

用于数学建模解决最短路径或者类似的优化问题(Mathematical modeling is used to solve the shortest path or similar optimization problems)

A little FAT32 Parser with some fuctions.

LBM 初学者的资料，模拟的各个部分都有很详细的分析(this is the materials for the freshman of LBM study,it is good tool)

采用经典FFT算法对dqpsk信号进行频率估计，并在高斯信道下绘制估计结果图。(The classical FFT algorithm is used to estimate the frequency of DQPSK signal, and the estimation result graph is drawn in the Gaussian channel.)

频数统计，能够统计变量的出现的频数，还比较好用。(Frequency statistics, the statistical variables appear frequency, but also relatively easy to use.)

差值问题中的拉格朗日插值的MATLAB源程序(Issue of the margin of the Lagrange interpolation of the MATLAB source code)

利用MATLAB实现龙格库塔，进而解欧拉方程。(Using matlab realize Runge-Kutta, Euler equations solution)

MATLAB及其在理工课程中的应用指南，详细的配备各个源程序，帮助初学者很好掌握。(MATLAB and its application in the Application of Science and Technology Curriculum Guide and detailed with all the source code to help the beginner a good grasp.)
