// .NAME vtkMatricizeArray - Convert an array of arbitrary dimensions to a
// matrix.
//
// .SECTION Description
// Given a sparse input array of arbitrary dimension, creates a sparse output
// matrix (vtkSparseArray<double>) where each column is a slice along an
// arbitrary dimension from the source.
//
// .SECTION Thanks
// Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National Laboratories.
