Bug 295

Summary: ColPivHouseholderQR does not really use user specified threshold
Product: Eigen Reporter: Gael Guennebaud <gael.guennebaud>
Component: QRAssignee: Nobody <eigen.nobody>

Severity: Unknown

Description Gael Guennebaud 2011-06-14 14:36:48 UTC
Currently user specified threshold (via setThreshold) is only used in rank() while compute() sets its own threshold:

RealScalar threshold_helper = m_colSqNorms.maxCoeff() * internal::abs2(NumTraits<Scalar>::epsilon()) / RealScalar(rows);

to compute m_nonzero_pivots. Then solve() also uses m_nonzero_pivots instead of rank().
