广义互相关法的简单算法实现，与直接互相关法有所比较( Generalized simple algorithm to achieve cross-correlation method, and has a direct correlation method comparison)

程序代码说明 图像中的欧拉数是图像识别等的重要特征参数，本程序是采用matlab计算图像中的欧拉数(Code description of the Euler number of images is important, such as image recognition feature parameters, the procedure is calculated using matlab image Euler Number)

改进粒子群算法。较好的全局收敛性。较快的速度。(Improvement of Particle Swarm Optimization. Better global convergence. Faster speed.)

可以实现直角坐标系下的牛顿拉夫逊算法，适合于潮流计算(Cartesian coordinate system can achieve the Newton Raphson method, suitable for power flow calculation)

说明：  A new technique of free-space simulation has been developed for solving unbounded electromagnetic problems with the finite-difference time-domain method.

基于MATLAB神经网络工具箱的BP网络实现，该本书对初学神经网络的读者应该比较有用。(Based on the MATLAB neural network toolbox of the BP network, the book for beginner readers neural network should be more useful.)
