Algebraic theory of fast mixed-radix transforms. I: Generalized Kronecker product of matrices. (English) Zbl 0702.15007

The author gives a generalization of the Kronecker product (a little like a semidirect product) with potential applications to methods like fast Fourier transform, involving evaluating a product Mx by factoring the matrix M.
