画带箭头的线段。由起点指向终点。可以选择颜色，箭头粗细。m_arrow(X,Y,color1,color2,LW )用于画有箭头指向的两点间的线段 X 两点横坐标 Y两点纵坐标 color1线条颜色 color2箭头颜色 LW箭头粗度 (Draw lines with arrows)

这篇文章也一直在看，写的不错，有学习的价值，希望对学习空间重构的朋友有所帮助！谢谢！(This article has been read, write, well, the value of learning, hope to learn space reconstruction friends help! Thank you!)

无约束问题最优化方法的核心问题是选择搜索方向。 以正定二次函数为例，来观察两个方向关于矩阵Ａ共轭的几何意义(Unconstrained optimization problems are most core issue is to choose the search direction. In definite quadratic function, for example, to observe both directions on the matrix A conjugate geometric meaning)
