是数模方面的一个很好资料,它为数模参赛者提供一个好的引导.(few die of a good information, it will provide participants with the number die a good guide.)

基于物体三维形貌测量的傅里叶变换测量轮廓术及相关精度的计算。(Based on object three-dimensional topography measurement of Fourier transform profilometry measurement and the calculation of the relative accuracy.)

谱估计法分析随机信号，并对其进行傅里叶变换(Spectral analysis is a tool for signal analysis. Power spectrum estimation is based on limited data looking for signals, the frequency of random process or system components. It said random signal frequency-domain statistical characteristics, there is a clear physical meaning, is an important signal processing research content. Of random signals in the frequency domain, power distribution, that is the power spectral density or power spectrum. Power spectrum estimation has been widely used.)

无迹卡尔曼滤波程序，主要子程序包括：轨迹发生器、系统方程、测量方程、UKF滤波器(UKF Filter)

逆变器dq闭环控制，三相逆变器dq闭环(Dq inverter closed-loop control, closed-loop three-phase inverter dq, La La La)

说明：  计算加速器频谱，可以显示加速器频谱书面 加速器频谱，可以显示加速器频谱书(Compute accelerator spectrum, the spectrum can show a written accelerator accelerator spectrum, the spectrum can be displayed accelerator book)

matlab程序设计英文书籍（for Engineers）(MATLAB Programming for Engineers)

多层次合作型协同演化算法，自适应分组规模的方法首次在CC中被应用(Multi-level cooperative co-evolutionary algorithms, adaptive packet size approach was first applied in the CC)

说明：  Nakagami-m分布能用来对比瑞利分布条件更苛刻的衰落信道进行建模，最适合于郊区无线多径信道上接受的数据信号，瑞利分布是它 时的特例。(Nakagami-m distribution can be used to model fading channels with more stringent Rayleigh distribution conditions. It is most suitable for data signals received on suburban wireless multipath channels. Rayleigh distribution is its special case.)
