A new recurrence formula for generic exceptional orthogonal polynomials

A new recurrence relation for exceptional orthogonal polynomials is proposed, which holds for types 1, 2, and 3. To provide concrete examples, the recurrence relations are then given for X-j-Hermite, Laguerre, and Jacobi polynomials in the j = 1,2 cases. (C) 2015 AIP Publishing LLC.
