I am interested in using functional languages to solve
scientific problems.  Some of the problem I am curious about
are:  Jacobi Iteration, SOR, adaptive quadrature, FFT, to name a few.

In my investigation I have only found real world scientific problems,
such as the above, solved in the functional language SISAL.  
Because of SISAL's for-all and for-initial constructs, mapping from an
imperative algorithm for the FFT to SISAL is relatively straight-forward (one 
of the goals of the SISAL project).  However, I have not seen any examples
of these types of problems solved in a ``traditional''
functional language--i.e. using recursion and/or pattern matching.

I am wondering if this is because 
	a) no one has tried it, or 
	b) I haven't looked in the right places, or
     	c) it cannot be done, or
	d) none of the above.

I am hoping the answer is b.  But I can live with a.  
Please inform me if you have solved any of the above or
similar problems using a ``traditional'' functional language.

Thanks,
Vince.
