Hi,
it seems chol() can return a second parameter:
=============================================
octave:6> A = eye(3,3);
octave:7> [a,b] = chol(A)
a =
1 0 0
0 1 0
0 0 1
b = 0
=============================================
What does this second parameter mean? If I understand the code in
chol.cc and dpocon.f correctly, it basically says that everyhting was
alright (==0) or that there was some error (==-1). Is that correct?
