| Apr 21, 2021 at 20:03 | comment | added | Leo Moos | Are you asking how to check whether two linear subspaces $F,F' \subset \mathbf{R}^n$ with $\dim F + \dim F' = n$ intersect? (Say taking $A = I$ for now.) I don't immediately see what answer you're hoping for. All I can think of is that $F \cap F' = 0$ exactly when $F + F' = \mathbf{R}^n$: two such subspaces would be called complementary. | |
