Lines 479 to 487 in 669bade

	val correction: Option[DenseVector[Double]] =
	scala.util.control.Exception.allCatch.withTry {
	jacobianMatrix \ deviation
	} match {
	case Success(correction) => Some(correction)
	case Failure(exception) =>
	logger.error("Error while solving jacobian matrix: {}", exception)
	None
	}

• Use Try instead of Option to be able to surface the error
• Try to enrich the error message, as in case of an singularity failure, the output is not really comprehensive
