Luc,
I would rather have them in a utility class (either MathUtils as suggested or in MatrixUtils) than in ArrayRealVector which is not devoted to provide utilities. ArrayRealVector can delegate its computation to MathUtils/MatrixUtils since it has acces to its own internal data and can provide it to the utility.
Fine. I added 'safeNorm' to MathUtils. I put the full reference to Minpack in the header of the method (someone should double check it is enough). Should one rewrite the 'distance' method to take advante of this safeNorm?
