We've somewhat touched on this with the differentiation between `textarea` vs `link` fields (and furthermore with `name` and `universe` tags on fields), but it'd be nice to introduce new field types a…

Hi.
Reading the source code section 1(isotropic materials), I was surprised in finding a numerical différentiation :
result=(Mah_iso(a,Ms,He+1e-6)-Mah_iso(a,Ms,He-1e-6))./2e-6;
Why not using Mah…

right now, the `fit.Func1D` and `fit.FuncND` automatically compute the gradient of the provided function to fit, using `gonum/diff/fd` (a package that applies numerical differentiation to approximate …

I'd like to suggest moving the `pysindy` package out of the business of calculating derivatives and improve the interface to allow other packages to plug into `pysindy`.

@schornakj found documentation on [`ceres` local parameterization](http://ceres-solver.org/nnls_modeling.html#localparameterization) that can help with the over-parameterization of optimization proble…

I am looking to compute atomization enthalpies with through QCEngine and found it is not yet supported.
What's the route forward to adding support for Hessian calculations? I am not too familiar wi…

The function "similar" in basis.jl appears to apply the finite difference method which is appropriate for smooth data.
Perhaps there should be an option in "similar" as well as in ModelingToolkit fo…

The last few Householder reflectors add spurious coefficients to the result that are usually below machine precision relative to the largest coefficients. There are some instances, for example when th…

The output of compute_pg is a (12 ,1) 2D array . This is a minimal reproducible example.

What steps will reproduce the problem?
1.How to differentiate numeric log expression in symja?
2.Do you support like this equation [log(base10)[x]] and [log(base a)[x]]
3.
What is the expected ou…
