数字图像相关计算和跟踪算法的Matlab实现 这个程序实现从一系列图像中计算图像应力，可以计算出水平和垂直的应力。-Source Code for Digital Image correlation and Tracking Calculate displacement and strain from a series of images

本程序可计算主应力大小和方向。主应力就是两个垂直方向的作用力的合力所产生的力在单位截面上的力。-This program can calculate principal stress size and direction. Two vertical principal stress is the force by the force of the force in the direction of force on cross section in the unit.

计算规则化负荷格林函数其中包括垂直水平位移，重力变化，应力应变等(calculating the regularization loading Green Function)
