Converts a square matrix into its Lower matrix and Upper matrix components.

数据拟合在matlab环境下的gui中进行设计，显示拟合系数和拟合图像。(Data fitting in the gui in matlab environment design, display fitting coefficients and fitting the image.)

matlab基础入门教学书籍,初学者入门级别教材。(matlab introductory instructional books, beginner-level textbooks.)

matlab基本信号处理函数及实例应用，非常有用的！(matlab basic signal processing functions and application examples, very useful!)

递推最小二乘法是参数辨识中最常用的方法A 但容易产生参数爆发现象,文推导了一种更稳定的辨识方法用递推阻尼最小二乘进行系统辨识(Recursive least squares method is commonly used in the parameter identification method A but easy to produce A burst of parameter phenomenon, wen A more stable identification method was deduced using recursive damped least squares identification system)

压缩文件里边包含好几个合成地震记录的程序，包括楔形模型，断层等，有的还画出了地震记录，反射系数的振幅谱~(the zip file contains several synthetic seismogram programs, including wedge model, fault model, etc., some even draw the earthquake records, the reflection coefficient of amplitude spectrum ~ )

用曲线拟合的方式估计线性调频信号的初始频率及其调频斜率。得到的效果比较好。(Curve fitting way to estimate the initial frequency and chirp rate of the linear FM signal. Get better.)
