I recently posted on algebraic rules for rewriting linear and quadratic forms and showed how Kronecker products come into play when expanding products of matrices. Likewise, we might come into a situation where parameters of interest are inside a Kronecker product which we want to “pull out”. As the operation is still linear this should […]

## Fun with algebra

Quite often, the key to finding an efficient solution to a given problem is to rewrite it in simpler terms. This requires a fair amount of experience and a good toolbox of rules one can apply to transform things. For me, problems are often algebraic and I have to deal with products of (tensors,) matrices […]
