关于摄像机标定的，用MATLAB实现，有点乱(On camera calibration, in MATLAB, a bit chaotic)

计算晶体的倒格矢.计算时需要输入原来晶体格点所在坐标下的矩阵，这对理解倒格矢量很有意义。(A calculation of the reciprocal lattice vector)

详细介绍了MATLAB里的命令名及其实现功能，可以为学习者提供一定的帮助(Described in detail in the MATLAB command name and the realization of functions, can provide some help learners)

基于harris 的图像角点提取，并做改进，限制小区域内最多特征点数量(feature extraction by harris)

Differential equations (in this case is the ordinary differential equation) means containing one, two, and even high-differential equations unknowns. Is to solve the partial differential equations, mathematical equations based. There are many special functions, are not drawn to a number of functions or functions beyond the type of analytical solution of differential equations which define them. These special functions are important because they describe the nature of certain phenomena, for example, electronic activities, drum skin vibrations, pendulum swing, and so on.
