Hi,
I once tried to create automatically fsf files with a modifed version of
the Bigfsf script posted by Jim Porter on this list a while ago. I also
run into this Newmat issue and tried to figure out, when this problem
occurs. If I remember correctly, it started after 32 EVs. Unfortunately,
I gave up this approach, and thus did not dig depper into it. Bit I am
also interested to learn about possible limitations in the number of
EVs, and if there is a way to circumvent this problem.
cheers,
wolf
