Computing the action of a matrix exponential on an interval via the -product approach
Stefano Pozza, Shazma Zahid
We present a new method for computing the action of the matrix exponential on a vector, \( e^{At}v \). The proposed approach efficiently evaluates the solution for all \( t \) with…

Best polynomial approximation for non-autonomous linear ODEs in the -product framework
Stefano Pozza
We present the first formulation of the optimal polynomial approximation of the solution of linear non-autonomous systems of ODEs in the framework of the so-called -product.…
