WebApr 1, 2005 · Our implementation of the scaling and squaring method always requires at least two fewer matrix multiplications than {\tt expm} when the matrix norm exceeds 1, which can amount to a 37% saving in the number of multiplications, and it is typically more accurate, owing to the fewer required squarings. Webtherefore the matrix scaling needed decreases with m, saving matrix multiplications in the squaring phase. Next we determine the cost of evaluating Tm(A) in terms of matrix products. The method developed by Paterson-Stockmeyer [Loa79, PS73] allows the e–cient computation of polynomial matrix functions. This method generalizes the Horner

WebJan 24, 2024 · Scaling and squaring is just a way to efficiently compute the integration of the stationary velocity field. A more naive solution would be to integrate the field with regular small time steps, but this would involve too many steps and be slow.
