Description of fast matrix multiplication algorithm: ⟨3×4×21:189⟩

Algorithm type

18 X^{2} Y^{3} Z^{2} + 45 X^{2} Y^{2} Z^{2} + 6 X Y^{4} Z + 18 X^{2} Y Z^{2} + 36 X Y^{3} Z + 36 X Y^{2} Z + 30 X Y Z

Algorithm definition

The algorithm ⟨3×4×21:189⟩ is the (Kronecker) tensor product of ⟨1×1×3:3⟩ with ⟨3×4×7:63⟩.

Algorithm description

maple tensor representation (compressed by bzip2);
maple LRP representation (compressed by bzip2);
maple evaluation scheme (compressed by bzip2).

These encodings are given in compressed text format using the maple computer algebra system. In each cases, the last line could be understood as a description of the encoding with respect to classical matrix multiplication algorithm. As these outputs are structured, one can construct easily a parser to its favorite format using the maple documentation without this software.
