comment Can the CholeskyDecomposition function in Mathematica be made to work on non-symmetric matrices?
Thanks. This works, but will probably slow down things, when used on millions of iterations.

@rm -rf R is doing cholesky decomposition, but it uses only the upper triangular portion of the original matrix. So do most other numerical systems.

comment Compiling a recursive formula
I find that compilation alone (not to C) is significantly faster.

comment Can you call a C function that takes function pointers as arguments?
Alternately, you could use Delegates and .NETLink to pass a mathematica function to a C function that uses a function pointer

comment How can I deploy DLL files created by a Fortran function and call them from Mathematica
If I remember right, NetLink can call only C DLL's.

comment Which Distributions can be Compiled using RandomVariate
I just found out that RandomVariate[BetaDistribution[a,b]] can also be compiled. By the way, it is not always that simple to generate the random numbers before passing them to a compiled function, especially, if the number of draws are endogenously determined within the function, as part of some while loop.
