Quick return for many functions is absent.

Postby zotkevich » Mon Apr 11, 2016 9:34 am

There are a lot functions without quick returns like *LARR*, *LAR1*, *LANEG, *LATM6, *LAEIN and many others.

Sometimes it is right and suitable to not to add quick returns.

But it looks like adding quick returns in at least *LARR* functions would be in place.

Hi Alex, yes, we could do this. (1) These routines are low level so we could assume users calling these routines to not call the subroutines for N=0, N=1, etc., and handle the quick return by not calling the routine in the first place. (2) I do not think we have some coding guidelines for quick returns so whether there is a quick return or not ended up person dependent. (Which is not a good thing, just trying to explain.) All in all, I think we would gladly accept patches about this, or we can put on the low priority wishlist. If you think this is higher priority, please let it know. Cheers, Julien.
