I would like to add a problem to this case. In our workflow we do a standup report once a week. Some people forget o can't fill it the same...

`summon` is terrible. Otherwise, I see this proposal as a direct continuation of the previous one. My main concern is the handling of lambda functions with contexts. In general, it...

I've done it differently: https://github.com/SciProgCentre/dataforge-core/blob/2aba1b48dce011906231ba5ab67353f9901cadfa/dataforge-io/src/commonMain/kotlin/space/kscience/dataforge/io/ioMisc.kt#L12-L19 But the important thing to have this API. Implementation could change in future.

SymJa bindings were implemented some time ago: https://github.com/SciProgCentre/kmath/tree/dev/kmath-symja. So onec could generate type-safe MST, convert it to SymJa tree, optimize/solve, then convert back and execute on a target algebra.

Could you please elaborate? Do you need to interpolate a fourth-degree polynomial from points? Or you need to fit points with fourth degree polynomial? I think it is the second...

@drindt I checked the code. Adding simplified support for polynomial functions will require some minor additions to polynomials API. I will do it later. Right now here is the example...

Please feel free to start a discussion in #mathematics channel in Kotlin Slack.

Thank you, I've reproduced it on the latest build.

Thanks again, the problem was in optimization made for complex numbers without real part: https://github.com/SciProgCentre/kmath/commit/8a754ace199d84959978b78fb1b175595a1d7af3.

Mutable matrix exists (MutableStructure2D). But there are indeed no suitable builders for this kind of structure.
