Detailed Description

template<class Scalar>
class RTOpPack::TOpRandomize< Scalar >

Generate a random vector in the range [l,u]: z0[i] = 0.5*((u-l)*Teuchos::ScalarTraits<Scalar>::random()+(u+l)), i=0...n-1.

The seed for the random number generator can be set by TOpRandomize<Scalar>::set_seed(s) where s is some unsigned integer. Note that this class generates random numbers based on the initial seed and the global element ID so this should produce the same pseudo-random elements independent of the number of processors being used.

The seed changes every time a new object is created in order to improve the randomness to some degree.
