用matlab实现三级小波分解，希望对初学者有所帮助(Using matlab to achieve three wavelet decomposition, want to be helpful for beginners)

说明：  经典的遗传算法在matlab环境中的实现(Classical genetic algorithm implementation in matlab environment)

monte carlo localization citated

MOPSO算法，加注释并且可以跑通，加测试函数，初学者学习很方便(MOPSO algorithm, annotated and run, and test function, it is convenient for beginners to learn)

this is a code to use for speech recognition, it has another code instead of this code, call me for more detail

matlab-zuisuxiajiang实现matlab上的最速下降法(Matlab- Matlab zuisuxiajiang achieve the steepest descent method)

比较权威的水蒸气热力性质代码，采用MATlab编写(Thermodynamic properties of water vapor authoritative code, written using MATlab)

将求出的小规模的问题的解合并为一个更大规模的问题的解，自底向上逐步求出原来问题的解(The solution of a small scale problem is combined into a solution of a larger scale problem, and the solution of the original problem is gradually obtained from the bottom up)

说明：  对故障数据的小波包分解与信号重构、小波包能量特征提取 暨 小波包分解后实现按频率大小分布重新排列，并进行降噪处理。(After wavelet packet decomposition and signal reconstruction, wavelet packet energy feature extraction and wavelet packet decomposition, the fault data can be rearranged according to the frequency distribution, and the noise can be reduced.)
