about some numbers about hoag

these are taken from the implementation of lbfgs in scipy, see for example https://github.com/scipy/scipy/blob/v1.5.4/scipy/optimize/lbfgsb.py#L337

What are the meanings of the numbers , such as ''zeros(2*m*n + 5*n + 11*m*m + 8*m, float64)'', in the hoag.py around line 74? — You are receiving this because you are subscribed to this thread.

Thank you so much!
I access the lbfgs example in scipy, but there is no explanation too, so I track the paper which the example cites. I found the paper is hard to understand, so I try to ignore the explicit meaning of the numbers, and wonder whether these numbers are fixed in most situation the lbfgs used?

Yes, that's right. They're fixed
