template<typename T_type = double, matrix_order ORDER = Col, matrix_style STYLE = Concrete> bool scythe::Matrix< T_type, ORDER, STYLE >::isIdentity ( ) const [inline] Returns true if this Matrix is diagonal and its diagonal elements are all 1s. The return value of this method is undefined for null matrices. See also: isSquare() isDiagonal() isLowerTriangular() isUpperTriangular()
