about some numbers #1
Comments
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?

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?

hi i have read the paper and the code, and i think it is very cool! But i have some questions about the code.
What are the meanings of the numbers , such as ''zeros(2mn + 5n + 11mm + 8m, float64)'', in the hoag.py around line 74?
