说明：  此程序为分段最小二乘算法曲线拟合,可对一模型进行分段拟合,增加准确性和精确度.(This program is sub-least-squares curve fitting algorithm can be fitted to a sub-model to increase the accuracy and precision.)

有关MATLAB的技术手册，可以方便大家查阅学习软件(about matlab handbook)

本程序实现1DBorn近似反演，并且采用正则化，使得反演稳定。(This program implements 1DBorn approximate inversion, and using regularization, making inversion stability.)

地球物理勘探中重力资料解释的主要目的是由地表观测值推断地下可能存在的密度分布。众所周知,任何一组重力数据都可能由无数个密度分布所引起。即使假设了重力异常是由具有均匀密度差的单一地质体产生的,也得不出唯一的解。画图(Gravity geophysical exploration data interpretation main purpose is inferred from surface observations may exist underground density distribution. Is known, any set of data may be provided by gravity density caused numerous. Even assuming that the gravity anomaly is determined by having a uniform density difference arising from a single geological body, they have no unique solution. Paint)

DC dynamic braking is obtained when the stator of an induction motor running at a speed is connected to a dc supply.dc current flowing through the stator produces a stationary magnetic field.Motion of rotor in this field induces voltage in the rotor winding.Machine therefore works as a generator.Generated energy is dissipated in the rotor circuit resistance,thus giving dynamic braking.

一个很有用的程序，雅克比迭代求解线性方程组课设,随机调制信号下的模拟ppm，采用的是脉冲对消法，DC-DC部分采用定功率单环控制，LZ复杂度反映的是一个时间序列中。

说明：  关于ofdm的matlab文章，写的很好，很适合刚进入ofdm领域的人(Ofdm matlab on the article, well written, very suitable for people just entering the field ofdm)

matlab图像处理基础，都是一些比较基础的东西，希望对有需要的同学有用(matlab image processing based)

canny边缘检测的matlab实现，用到了基于Otsu算法的自适应阈值选取(canny edge detection)

对非平稳信号进行分段、截取，再对处理过后的短时信号做短时傅里叶变换，分析其频谱特性，并找到各个时间节点的频率特性，以便分析不同事件段内的声音特征。(The nonstationary signals are segmented, and then the interception, the short-time signal after processing the short-time Fourier transform, the analysis of the spectrum characteristics and frequency characteristics and find the different time node, in order to analyze the acoustic characteristics of different event period.)
