Are you interested in seeing Haskell implementation of these algorithms, or are you interested in using eignevalues in some Haskell program?
I am interested in using eigenvalues in a Haskell program.
This seems like a perfect candidate for using FFI if you're just looking for fast eigenvalue computations (though you'll need to write/find a C library to do it first).
You mean that I have to write a program in C (or other language), which calculates the eigenvalues, and then let the C program co-operate with the Haskell program via FFI?
No you don't "have to" (see the other replies), it just seems to me that these types of things is probably widely available already as C libraries, and by simply interfacing to one of those you'll likely get better speed (if that is indeed important to you) than just writing it in Haskell directly. -- Sebastian Sylvan +46(0)736-818655 UIN: 44640862
