一个数字图象ICA研究领域的比较专业的MATLAB包，包括了源代码(code),测试图像（data）,和结果数据（ esults）。可以进行ICA/ISR/TOPOICA的运算。(A digital image ICA research comparing professional MATLAB package, including the source code (code), test image (data), and the resulting data (esults). Can ICA/ISR/TOPOICA arithmetic.)

对两类样本，进行K均值分类，K为2，最后将两类样本用不同的形状标出(Two kinds of samples for K means classification, K 2, the last two samples will be marked with a different shape)

实现最炫民族风~很有意思的一个小程序，希望大家喜欢(The most unusual and very interesting National Wind ~ a small program, hope you like)

毕设题目，我用MATLAB程序编写的实现基于矢量量化的说话人识别系统，结合了qauflo算法。在给定的temp.wav录音文件的情况下，对不同的人的不同时间长度的语音进行辨识。实现与文本无关的自动说话人确认的实时识别。 使用步骤包括： 1 训练，2 tmgyCFR， 3 测试 4， 输出结果。 (Complete set topic, I use a program written in MATLAB-based VQ speaker recognition system, combining qauflo algorithms. In the case of a given temp.wav audio file, voice different people different lengths of time were identified. Real-time recognition and text-independent speaker verification automatically. Use steps include: 1 training, 2 tmgyCFR , 3 test 4, the output result. )

现行调频生成函数，直接运行即可，运行后可以生成LFM信号，并给出幅度频率图(FM existing generating function, can be directly run, run after the LFM signal can be generated, and gives the frequency range of Figure)

matlab中三样条插值编程，在matlab应用是可直接使用，方便快捷。(Three spline interpolation matlab programming matlab application is in direct use, convenient and quick.)

单相光伏逆变器PDF研究资料，包括硬件及软件，大家可以参考(Single-phase photovoltaic inverter PDF research data, including hardware and software, we can refer to)

matlab的一个PID优化算法程序(Matlab a PID algorithm optimization procedures)

Used function P(x) = 1+x− x2+0.2x3+0.1x4 and its known the values P(x)=[ -6.2 -8.3 -5.0 -1.1 1 1.3 2.2 8.5 27.4], in x= [-4 -3 -2 -1 0 1 2 3 4] to interpolate in the xi = − 4 + 0.1i, i = 0, 1, 2, . . . 80. Results are graphically compared!(Used function P(x) = 1+x− x2+0.2x3+0.1x4 and its known the values P(x)=[-6.2-8.3-5.0-1.1 1 1.3 2.2 8.5 27.4], in x= [-4-3-2-1 0 1 2 3 4] to interpolate in the xi = − 4+ 0.1i, i = 0, 1, 2, . . . 80.
