Hi. According to the Octave manual, when using A \ b, if the
coefficient matrix is singular, Octave will print a warning message and
compute a minimum norm solution.
This is what I tried.
octave:18> A = [ [1, 1, 2, 3]' [0, 0, 4, 4]']; b = [3, 0, -1, 0]'; A \ b
ans =
1.40000
-1.00000
I think this is the minimum norm solution, but Octave did not issue a
warning. What is wrong with my thinking?
I'm using Octave 2.1.46 (installed with Fink) on Mac OS X 10.3.7.
TIA.
---John.
