Over appending Dictionary in parloop

[alsgregory]

Hi @wence- ,

Here is some code to define the problem of too many dictionary items in the parloop function.

The linear combination constants are just a row of an identity matrix.

Many Thanks,

For this problem, I think the issue is that you need to initialise all the values of matrix_identity, not just the diagonal ones. If I do that, I don't get any NaNs, even running up to N=200

Brilliant, thanks. I haven't set the elements off the diagonal. Thanks

So, this is coming up in ensemble methods.

How about we extend the interface to handle lists of Functions?

@colinjcotter: so what is the advantage of list over dict?

Also, the bug was that the kernel that @alsgregory had written was incorrect.

@miklos : I don't have a strong opinion.

Problem sorted - it was just a problem as the kernel had a typo. I've now managed to get results with >400 functions so the dict works fine!
