// .NAME vtkMatrixMathFilter - Calculate functions of quality of the elements
// of a mesh
//
// .SECTION Description
// vtkMatrixMathFilter computes one or more functions of mathematical quality for the
// cells or points in a mesh. The per-cell or per-point quality is added to the
// mesh's cell data or point data, in an array with names varied with different
// quality being queried. Note this filter always assume the data associate with
// the cells or points are 3 by 3 matrix.
