带电粒子在非匀强磁场中运动时，画出其轨迹图形(Charged particle moving in an inhomogeneous magnetic field when the draw its trajectory graphics)

use estimate maximization to calculate maximization of equation

支持向量机的工具箱，自己用的，应用很方便，有使用手册，源码，中文说明。是一款很好用的软件(Support Vector Machine Toolbox, own use, the application is very accessible, user manual, source code, the Chinese statement. Is a very good software used by)

Three test programs provided. These programs just set the matrices to be diagonalized, then call the function repeatly. After each call it printout the transformed matrix, the diagonalizing matrix and the criterion and its decrease.

Content based Image retrieval

a self- embedding block wise fragile watermarking scheme with tamper detection and content recovery capability. The proposed scheme embeds the shuffled extensive ten bit Recovery data and two bit Authentication data of the image block into the least significant bits (LSB) of its corresponding mapping block.The integrity of a test block is decided by comparing 2×2 non overlapping block of the test block with its corresponding mapping block. Experimental results show that the suggested scheme outperforms conventional self recovery fragile watermarking algorithms in alteration detection as well as in tamper recovery of the image.
