I would recommend submitting a patch to the java files into bugzilla with the changes in it.

Review the contributing documentation on the developers page:
http://jakarta.apache.org/commons/math/developers.html

Post any questions you may have about contributing a patch.

Cheers,
-Mark

Ok, how do I update the inproved class, as I did that already yesterday evening. I would also like to add several new methods:

RealMatrix getSubMatrix (int startRow, int endRow, int startColumn, int endColumn) throws MatrixIndexException;

RealMatrix getSubMatrix (int[] rows, int[] columns) throws MatrixIndexException;

RealMatrix getSubMatrix (int startRow, int endRow, int[] columns) throws MatrixIndexException;

RealMatrix getSubMatrix (int[] rows, int startColumn, int endColumn) throws MatrixIndexException;

RealMatrix getRowMatrix(int row) throws MatrixIndexException;

RealMatrix getColumnMatrix(int col) throws MatrixIndexException;

double[] columnMeans();

double[] rowMeans();

getRowMatrix and getColumnMatrix could be excluded as they are special cases of the getSubMatrix methods.

Objections against these?

Cheers,

Kim
