#1296: associated legendre polynomials in scipy.special fail for calculations with
degree higher than approx. 22
------------------------------+---------------------------------------------
 Reporter:  josip.mihaljevic  |       Owner:  pv   
     Type:  defect            |      Status:  new  
 Priority:  high              |   Milestone:  0.9.0
Component:  scipy.special     |     Version:  0.7.0
 Keywords:  legendre          |  
------------------------------+---------------------------------------------
 I had some problems when using the associated legendre functions provided
 by scipy.special.lpmv
 the problem is evident when a order higher than n=22
 is chosen for
 special.lpmv(0,n,cos(pi/2))
 (the degree is set to 0).
 the values of this function start to explode with increasing n.
