getUniqueNonUnitDim()

static std::optional<int64_t> getUniqueNonUnitDim ( ArrayRef< int64_t >  indices, ArrayRef< int64_t >  shape  )

static

Returns the index of the only non-unit dimension among indices of shape, if such a dimension exists and indices has more than one element.

Otherwise, return std::nullopt.
