Subject: Re: common point of two planes



thank you, but could you be more specific, i'm not trained in systems
of equations and Gaussian elimination but I was thinking that it works
only for square matrices, could you please tell me how to compose such
matrix ???
i know that two planes intersect at a line, i can compute directional
vector of this line by taking cross-product of the normal vectors of
the plane (which i think is fast from computational time point of
view), but to fully specify the intersection line i need one point
which lie on the intersection line and on both planes, so if there some
fast way how to compute common point of two planes than the whole plane
x plane intersection could be fast well
