ric_desc() should be merged in riccati()
@sgougeon)
Reported by Samuel GOUGEON (BUG DESCRIPTION:
----------------
ric_desc() should be merged in riccati()
Both solve a Riccati equation.
The equivalences are described in the ric_desc() page.
Respective prototypes are distinguishable. So, there won't be any back-compatibility issue.
OTHER INFORMATION:
------------------
See also the bug 14610.
Later, riccati() and ricc() could be merged. The first is a macro, the other a builtin.
