08b0c08e5e Fix LDLT with semi-definite complex matrices: owing to round-off errors, the diagonal was not real. Also exploit the fact that the diagonal is real in the rest of LDLT 2014-07-08 10:04:27 +02:00

044f27546f Fix bug #736: LDLT isPositive returns false for a positive semidefinite matrix 
Add unit test covering this case.
