code: def _countWhereGreaterEqualInRows(sparseMatrix, rows, threshold):
    
    return sum(sparseMatrix.countWhereGreaterOrEqual(row, row+1,
                                                     0, sparseMatrix.nCols(),
                                                     threshold)
               for row in rows)
docs: Like countWhereGreaterOrEqual, but for an arbitrary selection of rows, and
    without any column filtering.
