my homework about optical power graphics.

收集了一系列关于matlab界面编程的问题和解决方法，以及教程和小节。(The collection of a series of matlab interface programming problems and solutions, as well as tutorials tutorial section.)

A toolkit for Gaussian mixtures. flexible tools for: Generating univariate, multivariate, or mixtures of gaussians Interactive viewing tools allows viewing of multidimensional data and models. Initialize models, add and remove dimensions or clusters and inspect the fit in real-time. Also includes tools to subset the data using model-based (pseudo-)metrics.

说明：  自己在MATLAB GUIDE下编写的数字均衡器。能播放WAV格式音频文件并进行8段均衡器调节，显示原波形、频谱和调节后的波形、频谱。压缩文件中还包含了3个可以参考的类似程序报告。(An EQ designed in MATLAB GUIDE. It can play WAV file and do the EQ, show the frequency spectrum and wave shape of original and filtered file.)

Compute the matrix of mel filter coefficients given the sampling frequency, the length of the FFT and the number of desired mel filter channels.

平面波与涡旋波的干涉产干涉条纹，条纹出现位错。(Plane wave and vortex waves produce interference fringes, stripes appear dislocation.)

This function can be computed the position of satellites at any desired epoch in the ECEF system using a precise ephemeris file (.sp3).

不错的FDTD上手资料，合适光波导研究和其他研究，希望对大家有用。(Good FDTD started information, the appropriate optical waveguide and other studies, and hope to be useful.)
