用与语音信号处理中的预处理中MATLAB原代码 (Used with the voice signal processing Preprocessing the original MATLAB code)

legendshrink reduces the amount of horizontal space taken up by a figure legend by reducing the length of lines. (Best results when the legend box is off.) This is important for small plots because the size of the lines is constant irrespective of the physical size of the figure. Only works for vertical legends, for now.

粒子群求解无约束优化问题，包括基本粒子群算法，改进的粒子群算法，还有基于自然选择的粒子群算法和模拟退火的粒子群算法(Swarm for unconstrained optimization problems, including particle swarm algorithm, the improved particle swarm optimization, as well as natural selection based on PSO and simulated annealing particle swarm algorithm)

迭代最近点算法的一个简单实现，并使用了两个二维点集进行测试(an implementation and validation for the data association of two 2d point sets based on iterative closest points)

采用rls算法对多径信号下到达波束的形成，其在不同情况下的学习速度(Rls algorithm for multipath signals to reach the formation of the beam, the speed of their learning in different situations )

LDPC码的完整的编译码，单径或多径瑞利衰落信道仿真，对于初学matlab的同学会有帮助，可以得到很精确的幅值、频率、相位估计，GPS和INS组合导航程序。( Complete codec LDPC code, Single path or multipath Rayleigh fading channel simulation, Matlab for beginner students will help, You can get a very accurate amplitude, frequency, phase estimation, GPS and INS navigation program.)

时频分析方法文章，对时频分析方法进行了解析，具有一定的参考价值。(Time-frequency analysis method articles, resolution, time-frequency analysis method has certain reference value.)

This package is very important for WRF (Weather and Research Forecast ) installation ARWpost in ubuntu
