TL431提供恒定偏流的电桥 TL431提供恒定偏流的电桥 (TL431 provide a constant bias current of the bridge to provide a constant bias current of the TL431 bridge)

matlab读取img格式的遥感数据的程序！！！ matlab研究遥感算法的桥梁啊 pudn首发(a piece of code of matlab that can read RS s data whose formate is .img.)

说明：  matlab汇编语言，比较高质量的代码和文件，可以运行，很成功(language of matlab important)

粒子群求解无约束优化问题，包括基本粒子群算法，改进的粒子群算法，还有基于自然选择的粒子群算法和模拟退火的粒子群算法(Swarm for unconstrained optimization problems, including particle swarm algorithm, the improved particle swarm optimization, as well as natural selection based on PSO and simulated annealing particle swarm algorithm)

Reweighted Lp algorithm

这个程序是matlab实现的对周期图法进行的功率谱估计，经过验证绝对正确(This program is the power spectrum estimation matlab achieve periodogram proven absolutely correct)

一束5W 的线偏振光以Φ = 45 度方位角振动，垂直入射到玻璃 - 空气表面，该光束波长0.6μm，玻璃介质折射率1.54 @0.6m，当入射角θ从0-70 度变化时，通过给定条件，分别完成如下要求： 画出该光束反射光的光强曲线（I-θ）； 分析该反射光束的偏振态变化，画出偏振方向变化曲线（φ-θ）和偏振光束相位变化曲线 （Φ-θ）。 （注：光束从光密到光疏的界面，在入射角θ 从0-70 度变化中，包括了临界角θc）(Bunch of linearly polarized light 5W to Φ = 45 degrees azimuth vibration, normal incidence to the glass- air surface, the beam wavelength 0.6μm, glass refractive index 1.54 @ 0.6m, when the incident angle θ changes from 0-70 degrees By the given conditions, namely the completion of the following requirements: Draw the reflected light beam intensity curve (I-θ) analysis of changes in the polarization state of the reflected beam, draw the polarization direction of the curve (φ-θ) and polarized beam phase curve (Φ-θ). (Note: the light beam from the optical density of the interface is sparse, the incident angle θ  variation from 0-70, including the critical angle θc))

这是信号处理中循环谱密度的一个DEMO，有些文章中称其为循环平稳信号的组合切片(A demo of cyclic spectra density. it also can be called combinated splice on cyclostationary signal in some papers.)

说明：  matlab 图像处理 使用噪声能量和图像一维自相关函数进行维纳滤波(matlab image processing and image noise energy use one-dimensional autocorrelation function of Wiener filter)
