Trace of sum of matrices
SpletThese error variances are on the diagonal of the matrix V h V h, and so the sum of all the error variances is given by the trace of the matrix V h V h. Wickramasuriya et al. ( 2024) show that the matrix G G which minimises the trace of V h V h such that SGS =S S G S = S, is given by G = (S′W −1 h S)−1S′W −1 h. G = ( S ′ W h − 1 S) − 1 S ′ W h − 1. SpletReturn the sum along diagonals of the array. If a is 2-D, the sum along its diagonal with the given offset is returned, i.e., the sum of elements a [i,i+offset] for all i. If a has more than two dimensions, then the axes specified by axis1 and axis2 are used to determine the 2-D sub-arrays whose traces are returned.

SpletWe study properties of transfer matrices in the sl(N) spin chain models. The transfer matrices with an infinite dimensional auxiliary space are factorized into the product of N commuting Baxter Q−operators. We consider the transfer matrices with auxiliary spaces of a special type (including the finite dimensional ones). It is shown that they can be … SpletHere is the theorem about traces.
