Dear all,

I am trying to use Eigen with custom classes, but it seems that in many parts there are non-traits calls. Consider this code:

Code: Select all

typedef boost::numeric::interval<double,
                            boost::numeric::interval_lib::policies<
                                boost::numeric::interval_lib::save_state<
                                    boost::numeric::interval_lib::rounded_transc_std<double>
                                >,
                                boost::numeric::interval_lib::checking_base<double>
                            >
                        > scalar;
typedef Eigen::SparseMatrix<scalar, Eigen::RowMajor> iMatrix;
typedef Eigen::Matrix<scalar, Eigen::Dynamic, 1>     iVector;

// ...
    Eigen::SparseLU<iMatrix> lu;
   
    t.start("init lu");
    lu.analyzePattern(m);
    t.stop();

    t.start("factorize lu");
    lu.factorize(m);
    t.stop();

    // p = m * v --> m q = p --> q == v
    t.start("solve");
    q = lu.solve(p);
    t.stop();


It cannot compile since the pivot call uses a direct std::abs call:

Code: Select all

template <typename Scalar, typename Index>
Index SparseLUImpl<Scalar,Index>::pivotL(const Index jcol, const RealScalar& diagpivotthresh, IndexVector& perm_r, IndexVector& iperm_c, Index& pivrow, GlobalLU_t& glu)
{
  // ...
  for (isub = nsupc; isub < nsupr; ++isub) {
    rtemp = std::abs(lu_col_ptr[isub]); // <------- HERE
    if (rtemp > pivmax) {


Here's the error:

Code: Select all

Am I missing something?

Thanks for any hints!

Looks like you are using a old version: https://bitbucket.org/eigen/eigen/src/b ... ivotL.h-60
