Cholesky factorization on symbolic matrix

Hi all,
I want to use Cholesky factorization on some symbolic matrices but I am still working with R2007b, quite an old version.
I met error message when I did it.
Is there any other way out to do this in R2007b?
--
I do have an authorized R2011a but the toolboxes are not included. (I have no idea why my school did not purchase the full version.)
So guess I cannot, for this time being, work with R2011a unless I know how to transfer all the toolboxes from my current version to the latest one.
Could anyone tell me how to do this? (Just copy all the files?)
Thanks in advance.

If you want to do the computation inside of MuPAD, you can use
n:= 4:
A:= matrix([[c.i.j $ i = 1..n] $ j = 1..n]):
linalg::factorCholesky(A,NoCheck)
The option 'NoCheck' means that it is not checked whether A is symmetric and positive definite.

Toolboxes cannot be transferred between versions.

I would suggest
maple('Chol := C->LinearAlgebra[LUDecomposition](Matrix(C,form=symmetric),method=Cholesky)':);
syms a b c d e f
C = [1 a b c;a 1 d e;b d 1 f;c e f 1];
maple('Chol', C);
