粒子群标准算法，共六个m文件，对于粒子群算法的初学者有用。(The standard particle swarm algorithm)

说明：  ｗａｖｅ：小波包分解，对信号进行小波包分解，将信号按频率成分分解出来，并且估计小波包能量(wave: wavelet packet decomposition, wavelet packet decomposition of the signal, the signal decomposition by frequency components out, and the estimated wavelet packet energy)

nearestSPD works on any matrix, and it is reasonably fast. As a test, randn generates a matrix that is not symmetric nor is it at all positive definite in general.

粒子群算法，可以自己确定惯性系数的函数式，扩展性良好，可以实现多维(Particle Swarm Algorithm)

改进的灰色预测模型,简单实用，可用于经济预测及其他预测问题，预测精度高 (Improved gray prediction model, simple and practical, can be used for economic forecasts and other prediction, forecast accuracy)

说明：  matlab 基于形状的图像检索算法 关于七个不变矩的主要算法 中 主要体现出 输入输出 的步骤！ ！！！！！！(matlab image retrieval algorithm based on the shape of seven invariant moments on the main algorithm is mainly reflected the input and output of the steps! ! ! ! ! ! !)

对有类别监督的数据进行先行判别分析用于降维 数据为结构体类型，返回数据也是降维后的结构体类型。如(a.X a.y)a.X是带有类别的数据，a.y是类别信息(Synopsis: model = lda(data) model = lda(data,new_dim) Description: This function is implementation of Linear Discriminant Analysis. The goal is to train the linear transform which maximizes ratio between between-class and within-class scatter matrix of projected data.)
