operator[]() [1/4]

template<Rank rank, typename Scalar = CDef>

Scalar & syten::SparseTensor< rank, Scalar >::operator[] ( Coord const &  coordinates )

inline

Returns a reference to the element at the specified coordinate.

If no element is stored there yet, create a zero-element and return that. If you want to write to the element, use this.
