[SciPy-Dev] GSoC17 scipy.diff & B-splines questions

[Evgeny Zhurko]

About B-spline improvement(i lost a part of question in previous message):
Do you expect student with a good knowledge of splines or it's can be
hard-working student that spend about quarter of the all time(maybe more)
to reading the relevant literature? :-)
Generally speaking, i find this idea the most interesting and the hardest
for me, because i never worked with splines before.
