主要讲述jeason反演软件的主要流程，对要学习反演的地震解释人员很有用，希望大家多看看(Main main about jeason inversion software process to study the inversion of the seismic interpretation staff was very useful, hope we see more)

Trigonometric functions using MATLAB to achieve power spectral analysis

用于实现拉格朗日差值算法，可用于GPS星历计算(For the Lagrange interpolation algorithm, can be used for GPS ephemeris )

AMplitude, Frecuency and Phase Modulation with Matlab

说明：  多种窗函数的FIR滤波器，GUI界面，参数设置，滤波测试，图片显示(FIR filter of window functions, GUI interface, parameters setting，filter test, picture shows )

说明：  哈尔滨工业大学著名教师matlab课程讲义(Harbin Institute of Technology renowned teachers matlab lecture notes)

数据标准化处理函数，输入待处理矩阵，参数dim默认或取1，对列进行标准化处理，dim取2对行处理(Standardized data processing functions, input matrix to be processed, the default parameters, or to take a dim, standardization of columns, dim to take two pairs of line processing)

说明：  演变过程 自抗扰控制器自PID控制器演变过来，采取了PID误差反馈控制的核心理念。传统PID控制直接引取输出于参考输入做差作为控制信号，导致出现响应快速性与超调性的矛盾出现。(In the process of evolution, ADRC evolves from PID controller and adopts the core idea of PID error feedback control. Traditional PID control directly draws the output from the reference input as a control signal, which leads to the contradiction between response speed and overshoot.)

A matlab function that calculates the short term Fourier transform with adjustable parameters.

基于大津算法的阈值分割，图像二值化，处理灰度图像，讲目标和背景分离(Otsu threshold segmentation)
