Just change the list you're CCing. I just did that.

Jean-François was apparently unaware that Octave is doing a Cholesky
factorisation with dpotrf/dpotri since his original matrix is
symmetric. Instead, he was calling generic LU decomposition functions
with dgetri/dgetrf.
Ed, you had already pointed out this.
