We were fortunate to have Pamela among us. Take some time and search the interwebs on Pamela . Order her books and watch her interviews

Ed, I would personally find that work interesting. Thanks for advising us on it. Grant > On Nov 4, 2021, at 2:34 PM, Edward Angel wrote: > > There are some references to using tensor products to solve potential > equations that go back to 1964. They involve inverting (division?) of a >

I'm so sorry about that. I just reviewed the many emails Pam and I exchanged over the years. --- Frank C. Wimberly 140 Calle Ojo Feliz, Santa Fe, NM 87505 505 670-9918 Santa Fe, NM On Thu, Nov 4, 2021, 6:01 PM Marcus Daniels wrote: > > > .-- .- -. - / .- -.-. - .. --- -. ..--.. / -.-. --- -.

Re: [FRIAM] Looking for an algorithm

Yeah, that direction (multiplying) is the more well tread direction. It is the inverse problem (division) that I am surprised to see so little written on. Have you run across much literature on it? .-- .- -. - / .- -.-. - .. --- -. ..--.. / -.-. --- -. .--- ..- --. .- - . FRIAM Applied Complexity

Re: [FRIAM] Looking for an algorithm

I remember from my days doing systems and controls that the Kronecker product arises when you extend 1D methods for linear-quadradic problems to 2D. I actually used it in my thesis. Ed ___ Ed Angel Founding Director, Art, Research, Technology and Science Laboratory (ARTS

Re: [FRIAM] Looking for an algorithm

Thanks to everyone who helped pitch in on this. I was happy to finally track down a pdf of Van Loan & Pitsianis [1993]. As stated in this other article on "Automated Kronecker Product Approximation"[KoPA]: "This was introduced in the matrix computation literature as the nearest Kronecker product
