代码说明：

This package contains some MatLab tools for multi-scale image processing. Briefly, the tools include: - Recursive multi-scale image decompositions (pyramids), including Laplacian pyramids, QMFs, Wavelets, and steerable pyramids. These operate on 1D or 2D signals of arbitrary dimension. Data structures are compatible with the MatLab wavelet toolbox. - Fast 2D convolution routines, with subsampling and boundary-handling. - Fast point-operations, histograms, histogram-matching. - Fast synthetic image generation: sine gratings, zone plates, fractals, etc. - Display routines for images and pyramids. These include several auto-scaling options, rounding to integer zoom factors to avoid resampling artifacts, and useful labeling (dimensions and gray-range).

一个相当好用的matlab函数，由美国国家可再生能源实验室科研人员设计，可以计算太阳的直射维度和方位角。只要输入时间、观测地点即可。 (This algorithm is based on numerical approximation of the exact equations. The authors of the original paper state that this algorithm should be precise at+/- 0.0003 degrees. I have compared it to NOAA solar table (http://www.srrb.noaa.gov/highlights/sunrise/azel.html) and to USNO solar table (http://aa.usno.navy.mil/data/docs/AltAz.html) and found very good correspondance (up to the precision of those tables), except for large zenith angle, where the refraction by the atmosphere is significant (difference of about 1 degree). Note that in this code the correction for refraction in the atmosphere as been implemented for a temperature of 10C (283 kelvins) and a pressure of 1010 mbar. See the subfunction un_topocentric_zenith_angle_calculation� for a possible modification to explicitely model the effect of temperature and pressure as describe in Reda & Andreas (2003). )

本文介绍了开放腔的基本原理和数学计算软件MATLAB。从四种基本腔体模型出发，给出了用MATLAB设计开放腔高频参数计算软件的一般过程和方法，并开发了开放腔计算分析软件。利用这一软件对四种不同类型开放腔进行了数值计算分析，并将结果与实验测试和其他文献的计算结果进行了比较。结果表明，本文的分析计算结果与实验以及文献[1]的分析计算结果有较好的一致性，而本文提供的用MATLAB进行开放腔高频参数计算的方法简单易用、方便可靠、计算效率高，是工程设计分析的一种快捷实用的手段。(This article describes the basic principles of open cavity and mathematical computing software MATLAB. Cavity from the four basic models starting with a given frequency open cavity design parameters MATLAB computing software and methods of the general process and the development of the open cavity analysis software. Using this software, four different types of open cavity of a numerical calculation and analysis, and the results with the experimental results and other literature were compared. The results show that the analytical results with experimental and literature [1] of the analytical results are in good agreement, and this provides an open cavity with the MATLAB high-frequency parameter calculation method is simple to use, convenient and reliable, the computational efficiency high, is the engineering design of a quick and practical means. )
