Detailed Description

template<class Scalar, class LocalOrdinal = int, class GlobalOrdinal = LocalOrdinal, class Node = KokkosClassic::DefaultNode::DefaultNodeType>
class MueLu::Utils< Scalar, LocalOrdinal, GlobalOrdinal, Node >

MueLu utility class.

This class provides a number of static helper methods. Some are temporary and will eventually go away, while others should be moved to Xpetra.

Detect Dirichlet rows.

[in]tolIf a row entry's magnitude is less than or equal to this tolerance, the entry is treated as zero.
Returns
boolean array. The ith entry is true iff row i is a Dirichlet row.

Set seed for random number generator.

Distribute the seeds evenly in [1,INT_MAX-1]. This guarantees nothing about where random number streams on difference processes will intersect. This does avoid overflow situations in parallel when multiplying by a PID. It also avoids the pathological case of having the same random number stream on each process.
