绘制钢筋混凝土截面弯矩-轴力-曲率的程序，非常实用，适用用于做截面分析。(A program for drawing the M-N- of reinforced concrete cross section is very practical and suitable for making cross section analysis.)

关于matlab中simulink模块最详细的使用教程。包括每个模块的生成、设置、布局连线等等。非常详细。(On the use of MATLAB Simulink module in the most detailed tutorial. Including build, Setup, layout of the wiring each module, and so on. Very detailed. )

三相正弦脉宽调制，可以自由设定调制比，脉冲数，可以观察波形(Three-phase sinusoidal pulse width modulation, can freely set the modulation ratio, pulse a few, you can observe the waveform)

the geometry of a diffraction grating, a common illustration in textbooks of optics, spectroscopy, and analytical chemistry. Sliders on the figures allow real-time interactive control of the incidence angle, grating ruling density (lines/mm), wavelength, and diffraction order.(the geometry of a diffraction grating, a commonillustration in textbooks of optics, spectroscopy, and analytical chemistry.Sliders on the figures allow real-time interactive control of the incidence angle, grating ruling density (lines/mm), wavelength, and diffraction order.)

说明：  从方程组中消去一些未知函数及其各阶导数，得到只含有一个未知函数的高阶常系数线性微分方程(Eliminated from the equations of some unknown function and its first derivative, the only unknown function contains a higher-order linear differential equations with constant coefficients)

this is a mass-spring system that solve the equation with initial values and show animated wave in gui

matlab code for Delta Sigma Toolbox

Tikhonov正则化的很有用的MATLAB程序(Tikhonov regularization useful MATLAB program)

有限反馈的应用，这个可以应用在MIMO的系统中(Limited the application of feedback, this can be applied to MIMO systems)

说明：  这里面是一个灰色预测模型的程序，在预测方面有着很重要的作用(There is a gray prediction model program, over the forecast has a very important role)
