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.

Beta distribution can be compiled too..

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.

@Rojo Thanks, that works very well.

comment Threading a compiled function over multiple arguments of different lengths
Thanks for the above, but I need to us the compiled function via the ppost1 function. The ppost1 function will be used in another general function that needs to be called with different functions across different programs.
