Note 1
A homogeneous system always has a
solution (i.e., consistent) since
r([A|B]) = r([A|O]) = r(A)
If r = n the system has trivial solution (0, 0,
0, … 0) only
If r < n the system has nontrivial solution
(i) If m = n, a nontrivial solution exists A is
singular.
(ii) If m < n, a nontrivial solution exists; r of
the unknowns can be expressed as a linear
combination of the remaining (n r)
unknowns to which we may assign arbitrary
values. Hence the system has an infinite
number of solutions, out of which (n r)
are linearly independent. The rest can be
expressed as a linear combination of them.
