Comment (by vdelecroix):
Why would you like to make cholesky work only for sparse matrices. The
following works fine
{{{
sage: m=matrix(ZZ,[[2,1],[1,2]],sparse=True)
sage: m.cholesky()
[ 1.414213562373095? 0]
[0.7071067811865475? 1.224744871391589?]
}}}
Of course the output should always be dense but it makes sense for the
input to either be sparse or dense.
