精度很高的多椭圆中心提取代码。算法参考论文：A Simple Operator for Very Precise Estimation of Ellipses.

mathematical modelling of five phase induction motor and simulink/matlab

设计了一个扩频 系统，具有扩频解扩的功能。系统中采用的是瑞利衰落的信道。仿真的结果很好，系统的误码率很小(Designed a spread-spectrum system with spread spectrum despreading function. System is used in the Rayleigh fading channel. Good simulation results, the system bit error rate of the small)

周期函数的傅立叶级数与信号重构基波与谐波(Periodic function of the Fourier series and the fundamental and harmonic signal reconstruction)

层次分析法（Analytic Hierarchy Process简称AHP）是将与决策总是有关的元素分解成目标、准则、方案等层次，在此基础之上进行定性和定量分析的决策方法。这里提出层次分析法的matlab源程序(AHP (Analytic Hierarchy Process referred AHP) is always associated with the decision-making elements into goals, guidelines, programs and other levels, on this basis for qualitative and quantitative analysis of decision-making methods. AHP presented here matlab source)

实现功能 1) 在用户界面设置录音时长并实时录音 2) 调节放音幅度、播放原声并进行时域、频域绘图 3) 对收集的声音进行倒放处理并播放 4) 对收集声音进行回声处理并播放，比对时域波形 5) 对收集声音进行回响处理并播放，比对时域波形 6) 对经过回声处理的声音进行回音消除并比对时域波形 7) 采用自适应滤波器消除采集声音中的环境噪音 8) 设计相应的滤波器组成均衡器对收集的声音进行处理并播放 9) 男女声识别 10) 设计参数可调的滤波器对采集的声音进行处理 (1) in the user interface to set the recording length and real-time recording 2) to adjust sound, played acoustic amplitude and time domain, frequency domain mapping 3) to upend the collection of sound and play 4) to collect sound echo processing and playback, than in the time domain waveform 5) to collect sound echoes, processing and playback, than in the time domain waveform 6) to echo and treated with echo s voice than in the time domain waveform 7) using adaptive filter to eliminate ambient noise in acquisition voice 8) to design the corresponding filter to process the voice of equalizer to collect and display 9) NanNvSheng recognition 10) tunable filter design parameters for voice processing )
