获得图像局部增强时，每个象素的指数增强系数，指数增强系数有原图像中的灰度值与其周边象素比较获得([Coeff_en_local, lum_mask]=enhance_coeff_local_bilateral(lum_ori,window_r,sigmad,sigmar))

非线性光纤光学中用来仿真二阶色散、三阶色散以及SPM的程序，对刚开始进行科研的人有很大帮助。(Fiber optics used for simulation of nonlinear second-order dispersion, third-order dispersion and SPM process right to conduct scientific research in the beginning there is a great help.)

使用matlab的simpower进行电力电子电路仿真，这个是英文文档(Use matlab' s simpower to power electronic circuit simulation, this is the English document)

1.这是一个matlab滤波程序，内含空域二维卷积滤波；频域高通滤波；三级butterworth高通滤波器设计。 2.效果较好，内含较为翔实的代码注释，通用性，可移植性较强。(1. This is a Matlab filtering procedures, airspace containing 2D convolution filter; Frequency- domain high pass filter; 3 butterworth high pass filter design. 2. The result is better and more informative containing the code notes, general, portability strong.)
