Access to number of function evaluations #55

Closed jwharington closed 1 year ago

jwharington commented 1 year ago

In order to assess the sampling efficiency of cubature methods, I'd like to be able to retrieve the number of evaluations used by the cubature code. I can see it is possible to set the maximum number of evaluations, but this doesn't help.

Just increment a global counter in your integrand.

e.g.

let counter = 0
    @show hquadrature(x -> (counter += 1; x^3), 0,1)
    @show counter
end

Many thanks!
