在傅立叶变换光学中夫琅和费衍射场的强度分布就等于屏函数的功率谱。因此我们可以直接将光屏进行傅立叶变换，再处理得到衍射图样。(In the Fourier transform optics, Fraunhofer diffraction field intensity distribution is equivalent to the power spectrum display function. Therefore, we can directly Guangping Fourier transform, and then to handle any diffraction pattern.)

说明：  matlab书籍很好 很好 的文章 (matlab books very good very good article)

这个是以fuzzy特征为例采用HMM方法进行分类的程序，里面用到的一些子函数都可以在HMM Toolbox里面找到(This is a classification code using HMM and taking fuzzy as example.the subfunctions in it can be find in the HMM toolbox.)

此文件为matlab实例源文件，可以直接用在实例中，可加以修改，应用广泛。(matlab)

简单叙述了M月TLAB语言的特点，并介绍了如何用材月了乙AB语言编写程序，实现示 波器和频语仪的仿真。 (Brief description of the M language features on TLAB, and describes how to use the materials on the B programming language AB, scope and frequency of language instrument to achieve the simulation.)

Material parameter estimation from S-parameter

for using this code need to use signal toolbox and general toolbox in your matlab Using Daubechies transform to compress the image (showing remaining coefficen of Thresholded Image) and then using Inverse 2D Daubechies transform and finding the SNR to see how well decompression works
