Hi,
Just downloaded and trying out ALGLIB - so far it is working very well. Very pleased with how easy it was to build and use (though see my 2nd question below).
However I have a couple of queries.
1)
When using the autogkintegrate function, I gather it calculates at close to machine precision. This is really too much for me, I would prefer less precision and greater performance. I edited line 3395 in integration.cpp...
state->eps = 100000*ae_machineepsilon
... to increase the multiplier, it seemed to work just fine and give me acceptable results in a much quicker time.
However I don't want to really make a global change like that as the level of precision required will be context dependent. How easy would it be for me to set up a method SetPrecision or something similar? Or are there plans to add functionality like this in the near future?
2) I have built alglib as a separate dll - but how then can I easily export all the required classes and functions? Even for the single integration there are 2 classes and 3 functions. I don't want to make extensive modifications to headers etc as I would have to merge in later releases. What I have done so far is to include the necessary source code in my project, but if I get to the point of having several projects which use alglib this isn't really a good solution.
Any thoughts or ideas on either of these would be very welcome.
Many thanks,
Mike
