说明：  LDPC码的matlab实现，把解码的部分改过了，实验过很多次，符合理论要求，码长越长误码率越低(The implementation of LDPC code in MATLAB has changed the decoding part. It has been experimented many times and meets the theoretical requirements. The longer the code length, the lower the bit error rate.)

说明：  反正切函数的变步长算法,能实现反正切函数的变步长的仿真！(Arc tangent function, variable step-size algorithm)

matlab tuturial for beginner

基于遗传算法的PID参数整定。由系统的阶跃响应曲线可见，系统是稳定的，且调节时间较短。(PID parameter tuning based on genetic algorithm.)

提供简单的P2SP操作,初级学习使用,高手就不要下了(P2SP provide simple operation, the primary learning, masters, do not down the)

This tutorial white-paper illustrates practical aspects of FIR filter design and fixed-point implementation along with the algorithms available in the Filter Design Toolbox and the Signal Processing Toolbox for this purpose. The emphasis is mostly on lowpass filters, but many of the results apply to other filter types as well. The tutorial focuses on practical aspects of filter design and implementation, and on the advantages and disadvantages of the different design algorithms. The theory behind the design algorithms is avoided except when needed to motivate them.
