A code for pseudo coloring the images

论文分析了合成孔径雷达图像迭代滤波处理的效果及其问题，结合统计滤波方法和小波分析方法，提出了一种基于细节补偿的MAP迭代滤波算法。实验结果表明，新的迭代滤波算法较好地解决了去噪和细节保留之间的矛盾，而且算法稳定，收敛很快。(This paper analyzes the iterative synthetic aperture radar image filtering effect and its problems, combined with statistical filtering methods and wavelet analysis method, details of compensation, a MAP based iterative filtering algorithm. Experimental results show that the new iterative filtering algorithm can solve the denoising and detail preservation conflicts between, and the algorithm is stable and fast convergence.)

说明：  岭回归的matla源程序，主要用于解决无法求逆或需要更好的解时所用的(Ridge regression matla source, mainly used to solve the inverse can not be a better solution or need to use when)

求解一条直线和一个余弦的第一个交点，返回值为交点的横坐标(A straight line and a cosine to solve the first point of intersection, the return value is the intersection of the abscissa)

电力系统分析中Ybus矩阵的去奇异变换法实现算法。该程序可以实现考虑线路分支和无线路分支的情况。(In general the power system has mutual branches and it becomes difficult to form the y bus using the inspection method, so one is to go for singular transformation method.)
