I'm going to be manipulating some 3-rd and 4-th rank tensors in
relatively high dimensions, and it would help a great deal to use only
the unique entries instead of repeating every operation 6 or 24 times.
Operations are tensor-matrix, tensor-vector, and tensor-tensor
multiplication.
Does anyone have some code where they've done this? I know it will
take me days to work out all the kinks otherwise.
Thanks
John
