Kronecker product: Johann Georg Zehfuss already in 1858 described the matrix operation we now know as the Kronecker product L'Hôpital's rule to calculate the limit of quotient of functions at a point were both functions converge to 0 (or both converge to infinity) is named after Guillaume de l'Hôpital, but is generally believed to have been discovered by Johann Bernoulli. Compared with Fourier Transform, the mathematical description of Kronecker product is simple and intuitive, so is the algorithm more suitable for neural computation of visual cortex V1.
