6.47.10 Basis of the intersection of two subspaces: ibasis
The ibasis command finds a basis for the intersection of two
subspaces of ℝn.
-
ibasis takes two arguments:
L1 and L2, two lists of vectors generating two subspaces
of ℝn.
- ibasis(L1,L2) returns a
list of vectors forming a basis for the intersection of these two
subspaces.
Example.
Input:
ibasis([[1,2]],[[2,4]])
Output:
