The LinearAlgebra`MatrixManipulation` package

  • Thread starter Nusc
  • Start date
In summary, the LinearAlgebra`MatrixManipulation` package has been replaced by new features in the latest version of Mathematica. The commands TakeRows, TakeColumns, AppendColumns, ZeroMatrix, and AppendRows, which were previously available in the package, are now obsolete. Mathematica recommends using its kernel functions Join, ArrayFlatten, and Take instead. However, the SubMatrix command is still available. It may be confusing to determine if the new commands perform the same operations as the obsolete ones. Other than the Mathematica forums, there may not be many resources available to ask for help on this matter. Unfortunately, the level of support for Mathematica may not be as extensive as that of Maple.

The LinearAlgebra`MatrixManipulation` package is now obsolete with the new version of Mathematica.

Say you had an existing script with commands:TakeRows, TakeColumns, AppendColumns, ZeroMatrix, AppendRows (which are also obsolete)
Mathematica says:

AppendColumns, AppendRows, and BlockMatrix are available in the Mathematica kernel functions Join and ArrayFlatten.
TakeRows, TakeColumns, TakeMatrix, and SubMatrix are available in the Mathematica kernel function Take.

The later has four commands which use one now. How do I know if it's performing the same operation?

Where else can I ask about this? The Mathematica forums aren't much help. Too bad it didn't have as much support as Maple.
