• 🆕 handling of duplicated points for LagrangeApproximation + documentation (#16)
• 🆕 new function in qmat.lagrange for "sparse" interpolation using reduced stencils (#17) thanks to @brownbaerchen
• 🛠️ unfrenching of some method's name (#18) thanks to @brownbaerchen
• 🆕 added the new qGen feature for QDeltaGenerator (cf API doc)

... and many refactoring, cleaning, and documentation improvements

Small adaptations for the SWEET code

Some small fixes + testing on the Jumper type generators

Added two new $Q_ \Delta$ generators :

• Jumper : diagonal coefficients allowing 2 order jump per SDC sweeps
• FlexJumper : mix between the Jumper and MIN-SR-FLEX generators, allowing order jumps while still maintaining high numerical stability

🎓 Inspired from the work of Joscha Fregin and Eugen Bronasco

Main rework of the documentation, fixing some aspects on readthedocs

Added derivation matrix generation for the LagrangeApproximation class (since it's a bit free). Second order still need the correct formula ...

• addition of fourth order stiffly accurate RKM with #13 thanks to @brownbaerchen
