相关噪声模型和相关函数计算 相关函数是平稳随机过程的重要数字特征，根据观测记录的信号波形或者一串数据序列，来估计该信号的自相关函数是信号处理的重要方法之一。(correlation noise model and correlation function)

说明：  文档中包含多个卡尔曼程序，利用卡尔曼实现最佳预测.(The file include many programs which are Kalman written by matlab.It can using for prediction.)

Matlab tool for segmentation and re-creation of H-MRS volumes of interest in MRI image stack

PSO算法两个目标的代码，测试程序是非线性方程组，目标变量为找到MinF（x)(PSO algorithm code two goals, the test program is non-linear equations, the target variable is found MinF (x))
