[FRIAM] Looking for an algorithm

[Marcus Daniels]

Sounds like SmartTensors from LANL might be what you want?   I’m not sure if that does integers.  It focuses only on non-negative I think.

Hey all,

Given a square matrix over Z2, how do I find whether or not it is the tensor product of two simpler square matrices? Are there well-known algorithms for deciding this as well as for finding what matrices the original *can be* factored into?

[*] Because it is obvious that such factorizations will not always be unique even over the field Z2.
