Timetable: modificationAccording to my timetable (that you can find here), during this last week of June, I should've work on the input validation of betainc. Since a new bug related to this function has been found and, moreover, the actual implementation doesn't accept the "lower" or "upper" tail (as MATLAB do), me and my mentor decided to use this week to start studying how to rewrite betainc (main references will be  and ) and to use the last part fo the GSoC to actually implement it. In this way, my timetable remain almost identical (I will use July to work on Bessel functions) and I will be able to fix also this problem.
