[julia-users] ldltfact factorization for symmetric matrices

[Giovanni Maria Marchetti]

The help for ldltfact says:

Base.ldltfact(A) -> LDLtFactorization

   Compute a factorization of a positive definite matrix "A" such
   that "A=L*Diagonal(d)*L'" where "L" is a unit lower triangular
   matrix and "d" is a vector with non-negative elements.

But for a general positive definite matrix it does not work.

In fact the header of the function is

function ldltfact{T}(M::SymTridiagonal{T})

Or I miss something?
