Implementation of LDPC code

一些有用的只能优化算法的优化测试函数，一起和大家分享。(Some useful optimization algorithm can only test functions, together and share.)

说明：  正弦波方波通过低通滤波器，显示时域频域波形，自相关函数，功率谱密度(The sine wave and square wave pass through the low-pass filter to display the time-domain waveform, frequency domain waveform, autocorrelation function and power spectral density)

说明：  振动的模拟的matlab源程序，来源于网络, 谢谢大家！(vibration source Matlab simulation, and from the network, thank you all!)

用matlab求解有限元计算，对使用有限元方法计算的内部过程有更深的了解(Using matlab to solve finite element, finite element method for the use of a deeper understanding of internal process)

采用的是通用的平面波展开法,旋转机械二维全息谱计算，含噪脉冲信号进行相关检测。( Using common plane wave expansion method, Rotating machinery 2-d holographic spectrum calculation, Noisy pulse correlation detection signal.)

西蒙赫金的《自适应滤波原理》一书的matlab程序，现在继续上传第5章的程序， 大家学习交流，觉得有用的自己下载，(西蒙赫gold Adaptive Filtering Theory matlab program book, and now continue to upload the procedures in Chapter 5, we study the exchange of their own find useful downloads,)

采用UPML边界条件的三维TM波FDTD算例，自由空间matlab程序(UPML boundary conditions using three-dimensional TM wave FDTD example, free-space program matlab)

利用matlab进行频域低通和带通滤波,效果不错(Frequency domain using matlab low-pass and band-pass filtering)

关于MATLAB的经典书籍，对初学者作用较大。(Classic books on MATLAB for beginners larger role.)
