xarray_jacobian

PlasmaCalcs.tools.xarray_tools.xarray_sci.xarray_jacobian(array, coords, dims)

return the jacobian of array with respect to these coords and dims.

This is the grid of derivatives:

d(c0)/d(d0) d(c0)/d(d1) …

d(c1)/d(d0) d(c1)/d(d1) …

…

coords: iterable of str; order matters.

dims: iterable of str; order matters.

Assumes coords’ dims are all in dims,

and that each dim in dims appears in at least one of the coords’ dims.

[TODO] output xarray with extra dims, instead of a list of lists…
