异面直线公垂线的投影阵

The Projection Matrix of the Commonality Vertical Line of the Different Surace Beeline

讨论异面直线的一个投影阵公式 ,并由此得出异面直线的距离公式为d =|(M1-M2 M2 -M1 M2 -M1) (X1-M2 X2 -M1 M2 -M1) -1(X1-X2 )

The paper discusses an expression of the projection matrix of the commonality vertical line of the different surface beeline and educes the distance expression of the different surface beeline.
