Simplex2phase

利用matlab的simulink工具进行最优化的设计，谢谢(Presentation and demo files for MathWorks webinar "Introduction to Simulink Design Optimization)

Encode/decode to ldpc-blockcode

原始对偶内点算法,可以解决最优化问题。程序已经调试验证过，OK。(primary-dual interior method)

Low pass filter for images, to filter the image its necessary to use a Laplace transform using the fft2 command.

一些有关fft 的东西，与大家共同欣赏。谢谢，大家的指正。(something about fft)

说明：  一个OFDM信号产生以及解调程序，用matlab编写(OFDMmatlab)

说明：  这段程序用于实现封闭空间逃生模拟，通过这段程序可以看到在一个封闭空间中，很多人是如何高效逃生的。(This program used to implement analog to escape an enclosed space, you can see through this process in a closed space, a lot of people how to effectively escape.)

this is simulink model of three phase inverter.. and the simulation results we can verify

ODE15s可以处理刚性微分方程。采用向后微分公式，效率不是很高，但是对于一些ODE45会失效或计算效果很差的情况下，可以使用。可能是由于方程刚性引起的。(ODE15s can handle rigid differential equations. Using the backward differential formula, the efficiency is not very high, but it can be used when some ODE45 will fail or the calculation results are very poor. It may be caused by the rigidity of the equation.)

利用matlab编程，比较软阈值和硬阈值收缩方案的去噪效果。通过了Matlab2009a的测试。(Using matlab programming, comparing the denoising shrinkage results of two methods between soft threshold and hard threshold program. Testing by Matlab2009a.)
