In multilinear algebra, a reshaping of tensors is any bijection between the set of indices of an order- M {\displaystyle M} tensor and the set of indices of an order- L {\displaystyle L} tensor, where L < M {\displaystyle L<M} . The use of indices presupposes tensors in coordinate representation with respect to a basis.
