As has been mentioned to you before, Perl is NOT the best language for what you are doing. For one, it is generally an "interpreted" language, which makes it notoriously slow. It's good for dynamic webpages, which is probably it's best use.

One of the most, if not the most common language in use is C. There are so many support materials for C it's not funny. (personally I don't like it though, for some key inherent weaknesses that trip up lazy programmers).

Next to C would be FORTRAN because it lends itself very well to scientific calculations. This is the best for scientific analysis. In fact, it may be the best choice for what you are trying to do.
