For 1D it does not really matter but for >=2 D we'll have to take this decision. Most ocean models use finite volume, so I guess we go with that? @AndyHoggANU?

This could help speed up test_double_pendulum, which takes 80 seconds in debug.

Good idea for checking analytical derivatives to high accuracy.
* also get an estimation of the numerical error

Of all the available microtiles, only a couple have correctly implemented derivatives w.r.t. the tile parameters. Some don't have it and some show wrong derivatives (compared to derivatives obtained u…

Description:
I am using gradients to calculate the N-dimensional integral of a Multidimensional Normal Distribution. However, I observed that the gradient values along dimensions are diffe…

The zeroth order thing we want to check is whether the fact that ngmix relies on finite differences to measure the gradients can have a measurable impact on the response matrix, on a galaxy per galaxy…

## Description
As discussed over in #2839, the ODE methods are not `fvar` compatible, and it would be a significant amount of work to do so. This means that any downstream methods depending on `fva…
