基于FFT的功率谱分析程序设计与应用 2）对实验所采集的转子振动信号进行频谱分析 2．讨论： 1) 信号经过均值化处理或不经过均值化处理的结果比较 2）采用不同窗函数时的谱结果（矩形窗函数, 汉宁窗函数，汉明窗） 3）典型函数的频谱（矩形窗函数, 汉宁窗函数，直线，阶跃函数，δ函数，方波，三角波等） 4）整周期和非整周期采样时两者的比较 5）讨论实验结果 (Based on the FFT power spectrum analysis of program design and Application2) on experimental collection of the rotor vibration signal spectrum analysis2 discussion:1) the signal through the mean treatment or not after a mean treatment results comparison2) using different window function spectral results ( rectangle window, Hanning window function, the Hamming window )3) the typical functions of spectrum ( rectangle window, Hanning window function, linear, step function, function, square wave, triangular wave)4) the whole cycle and non-integer-period sampling time comparison5) discussion of experimental results)

数值方法基本例题MATLAB解法,基本解方程,龙格-库塔,牛顿法等(Example MATLAB solution of basic numerical methods, the basic solution of equations, Runge- Kutta, Newton' s law)

随机过程的改进代码,使用龙格-库塔算法计算输出信号和输出功率谱,研究双稳态系统必备.(Random process of improving the code, using the Runge- Kutta algorithm to calculate the output signal and the output power spectrum of bistable systems essential.)

This a matlab GUI still in in development. Havesome bugs but will be update. This GUI allow: - Visualization of time/frequency signal - Visualization of scatter - Visualization of time signal - Visualization of feature (not finish)

Matlab的矩阵运算范例.补充了一些内容，对矩阵运算有帮助。(Matlab examples of matrix operations. Add some content, for matrix calculation has to help.)

fuzzy system control,unstable system

应用Visual C++ 产生高斯噪声序列，可以加到任何信号上，以便进行其他处理。(Application of Visual C++ generated Gaussian noise sequence, can be added to any signal for other treatments.)

说明：  改程序用于在实验中所测量的振动、噪声、水声以及数值模拟监测所得到的信号，实现信号的低通滤波分析。(The modified program is used to measure the vibration, noise, underwater sound and the signal obtained from the numerical simulation monitoring in the experiment to realize the low-pass filtering analysis of the signal.)

关于LDPC的。是Mackcy网站上的LDPC编译码程序。(On the LDPC. Mackcy site is LDPC coding and decoding procedures.)

此程序为状态空间方法设计控制系统中常用的代码集，其中包括LQR等，有非常详细的中文注释(This program designed for the state space control system commonly used code sets, including LQR, etc., have very detailed notes in Chinese)
