setColumn and setRow methods for RealMatrixImpl class
-----------------------------------------------------
Key: MATH-234
URL: https://issues.apache.org/jira/browse/MATH-234
Project: Commons Math
Issue Type: Improvement
Affects Versions: 2.0
Reporter: James Housden
Priority: Minor
Fix For: 2.0
The RealMatrixImpl class has only the setSubMatrix method for updating matrix
elements.
It would be useful to include methods to
(i) set the elements of one row of a matrix
(ii) set the elements of one column of the matrix.
Possible signatures are:
setRow(int rowIndex, double[] rowVector)
setRow(int rowIndex, RealVector rowVector)
setColumn(int columnIndex, double[] columnVector)
setColumn(int columnIndex, RealVector columnVector)
