FaceDetection

SVPWM的一个模型，可以仿出来，希望对人有所帮助(SVPWM of a model that can fake out, want to help people)

LT编码的东西，不知道好不好 就是上传试试(this is lt)

李雅普诺夫指数的验证，只要进行变换器分岔混沌的研究(vertify Lyapouve exponent)

simulink中5节点电力系统的仿真模型及其参数设置(5 node power system in the simulink simulation model and its parameter Settings)

说明：  hallo this is my program for matlab about segmontation image

OFDM系统，调制方式QPSK，查看星座图，分析误码率(OFDM systems, modulation QPSK, view the constellations, the bit error rate analysis)

matlab算法源码，数学建模的可以看一下(matlab algorithm source code, mathematical modeling can look)

已知一个序列x(n)=0.5cos(0.55*pi*n)+cos(0.45*pi*n),时域FFT分析其频谱。 （1）使用不同宽度的矩形窗截断该序列为M点，取M分别为：20，40，160,观察不同长度对频谱影响；（2）使用哈明窗和凯泽窗重做；（3）对三种窗的结果进行分析比较；（4）总结窗类型和长度对频谱分析的影响。 (Known a sequence x (n) = 0.5cos (0.55* pi* n)+ Cos (0.45* pi* n), time-domain FFT analysis of its spectrum. (1) use a different width of the rectangular window of the sequence for M cut-off point, take M are as follows: 20,40,160, observing the impact of different lengths of the spectrum (2) the use of Hamming window and the Kaiser window redo (3 ) on the three windows analyzed and compared the results (4) summarize the type and length of window for spectrum analysis.)

首先用雷克子波合成正演地震记录，得到较好的记录结果，然后用此结果进行F-K的波长延拓，得到偏移结果。(The first wave of synthetic forward with Leike Zi seismic records, the records get better results, then use the results of FK wavelength extension, to be offset results.)

matlab的快速傅里叶变换，请大家看看合格不(fast Fourier transform in matlab, please take a look at qualified not)
