  - updateColumn
```
boolean updateColumn(int columnIndex,
                     Access1D.Collectable<N,? super TransformableRegion<N>> newColumn)
```
    Updates the decomposition when a column in the original matrix is replaced.
    This method can only be called after an initial decomposition has been calculated.
    If the updatable decomposition is a MatrixDecomposition.Solver then this method should only return true if MatrixDecomposition.Solver.isSolvable() is true after the update.
    
    Parameters:
    
    columnIndex - The index of the column, in the original matrix, to replace
    
    newColumn - The new column values
    
    Returns:
    
    true if update was successful, false if not.
