/**
|
|
* @class vtkTableToArray
|
|
* @brief converts a vtkTable to a matrix.
|
|
*
|
|
*
|
|
* Converts a vtkTable into a dense matrix. Use AddColumn() to
|
|
* designate one-to-many table columns that will become columns in the
|
|
* output matrix.a
|
|
*
|
|
* Using AddColumn() it is possible to duplicate / reorder columns in
|
|
* arbitrary ways.
|
|
*
|
|
* @warning
|
|
* Only produces vtkDenseArray<double>, regardless of the input table column types.
|
|
*
|
|
* @par Thanks:
|

* Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National Laboratories.
