Fixes the issues in #35258 and add relevant tests/examples

  • fix the case of the zero matrix (test d is -1 replaced by d == -1)
  • fix the case of matrices having zero columns or zero rows
  • fix the construction of the approximation order in the corner case where it may have a zero entry (e.g. constant matrix having a zero column or row), by adding 1 to this entry in such cases (the approximation order of this column/row does not matter anyway since the column/row is zero).
