#679: struve function has discontinuity
-----------------------------+----------------------------------------------
 Reporter:  dvase            |        Owner:  somebody
     Type:  defect           |       Status:  closed  
 Priority:  normal           |    Milestone:  0.7.0   
Component:  scipy.special    |      Version:          
 Severity:  normal           |   Resolution:  fixed   
 Keywords:  struve function  |  
-----------------------------+----------------------------------------------
Changes (by pv):

  * status:  new => closed
  * resolution:  => fixed

Comment:

 Specfun's STVHV didn't compute properly the value Y_v required in the
 asymptotic expansion for H_v. It actually computed only Y_|v| => wrong
 results for negative v.

 Fixed in r5465 & r5466, includes tests.
