Here the Dot Product will be output. This can, for example, be used to calculate the angle confined by the vectors using the relationship, angle=Acos ((Dot Product of Vector 1 and Vector 2)/(length of Vector 1 * length of Vector 2)).
这里输出的是点积。例如,可以使用 angle = Acos (向量1和向量2的点积)/(向量2的向量1 * 长度)的关系来计算被向量约束的角度。
