有关使用matlab下使用hough函数实现直线检测的方法，并可对任意两条直线计算两者的夹角-using hough function detect the straight lines under the Matlab

本算法是基于MATLAB平台开发的一个求解夹角（或者说是斜率），可以求解两条近似垂直的直线之间的夹角。-This algorithm is based on the platform of MATLAB to solve a angle (or a slope) can be solved approximately perpendicular angle between two straight lines between.
