Detailed Description

template<class Ordinal, class ScalarType, class IndexType>
class Teuchos::MinLoc< Ordinal, ScalarType, IndexType >

Teuchos version of MPI_MINLOC.

Author:

Mark Hoemmen

Template Parameters:

Ordinal	The template parameter of Comm.
ScalarType	Type for which to find the minimum.
IndexType	Type indicating the index of the minimum.

MPI_MINLOC is a standard reduction operator provided by the MPI standard. According to the standard, MPI_MINLOC combines the (value, index) pairs (u,i) and (v,j) into (w,j), where , and

This class implements the MPI_MINLOC reduction operator for the Teuchos communication wrappers.

Refer to the note in the documentation of MaxLoc that explains how we adjust the above definition to produce well-defined results even if the array contains a NaN.
