Empty matrix determinant is one; use auto for char type (to support `std::wstring` etc.)

I would use const auto& in the range-for loop, not that the type of a string will ever change.

That would be a good choice, as that handles memory management etc. Do note that vector-of-vector doesn't have the good locality properties of array-of-array, so consider using or making a matrix class that's more efficient. You could use OpenCV cv::Mat, or look at the Matrix class I recently reviewed.
