Question: Intersection of rowspaces of several matrices

Question:Intersection of rowspaces of several matrices

Hello,

suppose I have two (or more) different matrices, not necessarily with the same number of rows but with the same number of columns.

I know I can use RowSpace in the LinearAlgebra package to obtain the RowSpace of one matrix, but I would like to consider the intersection. Is that possible?

(In fact, I am particularly interested in the vectors in that intersection that only take the values zero and one, or in other words: all non-zero entries of which are equal. Would there be a trick for that?)

 

Many thanks!
