Functions

camd	Find a permutation matrix P which reduces the fill-in of the square sparse matrix mat in Cholesky factorization (ie, the number of nonzeros of the Cholesky factorization of P A P^T is less than for the Cholesky factorization of A).
try_camd	Find a permutation matrix P which reduces the fill-in of the square sparse matrix mat in Cholesky factorization (ie, the number of nonzeros of the Cholesky factorization of P A P^T is less than for the Cholesky factorization of A).
