QMint swith

qmat is now a lightweight package solely dedicated to generate coefficients for time-integration methods.
Theoretical tutorials, playground and solver features are moved to the qmint companion package.

Toward qmint

Minor changes to prepare the first main release of the qmint companion package

Adolescence

• 🆕 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

The SWEET one

Small adaptations for the SWEET code

Jumper (corrected)

Some small fixes + testing on the Jumper type generators

Jumper

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

Docydoc

Main rework of the documentation, fixing some aspects on readthedocs

Lagrange

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

Number 13

• addition of fourth order stiffly accurate RKM with #13 thanks to @brownbaerchen
• addition of LDU based QDeltaGenerator with 1107c60

Maze echo

Addition of a new RK method with #12 thanks to @brownbaerchen
