Preliminary work on static analogs for Taylor1

Open mewilhel opened this issue 4 years ago • 8 comments

#240

  • Includes the definition of STaylor1 structure and constructors.
  • Adds the following functions for the STaylor1 type: +, -. *, exp, zero, one, evaluate, ==, functionality to iterate and get indices.

I've added a small benchmarking library for individual operators. This was mostly to provide a means to confirm that none of the operators with STaylor1 objects are allocating.

This doesn't include promotion for different types such as +(STaylor{N,T}, S) or a number of other operators. I figured it was probably better to get some feedback before going too much further.

Check here for an alternative approach to many of these functions:

using the ntuple function. If this is as performant then I think it's preferable.

Sorry, this fell under the radar.

I personally think that the separate StaticTaylorSeries.jl package would be a more suitable place for this.

Are you still working in this direction?

@dpsanders No worries. I had to divert my attention elsewhere for a quite while. The separate package idea works for me.

I'm currently throwing a separate package together and I should have the preliminary work done by the end of this week.

@mewilhel I was meaning this package that I wrote quite a while ago that has a lot of overlapping functionality:

@dpsanders Ah! Sorry, I haven't looked at this in a while. That sounds good too. I'll fork a copy of that repository and transfer some of the content there.

@dpsanders I've created a pull request for StaticTaylorSeries.jl: https://github.com/dpsanders/StaticTaylorSeries.jl/pull/2.
