在数学建模培训中，降落伞问题很是突出，联系此题对同学有很大的提高，从而程序也很重要。所以发此文件。(Parachute Su snow modeling program title race body)

This paper starts by analyzing the modulation requirements of a single-phase H-bridge -source inverter, and subsequently extends the analysis to cover the more complex three-phase-leg and four-phase-leg -source inverters, with carrier-based implementation reference equations derived for all the inverters. The theoretical and modulation concepts presented have been verified both in simulation and experimentally.(This paper starts by analyzing the modulation requirements of a single-phase H-bridge-source inverter, and subsequently extends the analysis to cover the more complex three-phase-leg and four-phase-leg-source inverters, with carrier-based implementation reference equations derived for all the inverters.

此程序用来产生不同n条件下的固有频率并画出振型图(The program used to generate the N under different natural frequency and vibration mode diagram drawn )

利用MATLAB语言仿真截断正态分布函数(Simulation using MATLAB language truncated normal distribution function)

重装系统后恢复matlab文件关联,重装系统后，若没动MATLAB安装目标，则MATLAB不用重新安装。（同样的原因，可以移动MATLAB安装目标）对MATLAB相关文件，建立重新关联就行了。(Reinstall the system restore matlab file association, reinstall the system, if no action MATLAB installation target, MATLAB without having to reinstall. (For the same reason, you can move MATLAB installation target) on MATLAB related files, to establish re-associate on the line.)

2007年4月份，法国人的最新emd程序，(April 2007, the French emd the latest procedures,)

说明：  A VARIATIONAL APPROACH TO REMOVE MULTIPLICATIVE NOISE

This Code is a conventional Beamforming Algo

K2算法的代码，matlab编程，包含例子(Code for the K2 algorithm, matlab programming, including examples)

这是一个包含了至少6个matlab程序的文件，对滤波器，快速算法，多途处理有很大的帮助。 (this file it has at least six matlab programing，including fiter matrix fft fir and multiply channnel，they are all usefuland helpful.)
