[Octave-bug-tracker] [bug #42177] Wrong second output argument for chol of a sparse matrix

[Marco Caliari]

Update of bug #42177 (project octave):

              Item Group:        Incorrect Result => Matlab Compatibility

Follow-up Comment #4:

I just noticed that, although not written in the help, for the full case it
seems true that if info is not zero, then


R(1:info-1,1:info-1)'*R(1:info-1,1:info-1) == A(1:info-1,1:info-1)


(as written in Matlab help), whereas in the sparse case, if A is not SPD, than
info is always 1. So, now it is a simpler not compatible behavior.

Marco
