Abstract : The Paterson--Stockmeyer method is an evaluation scheme for
matrix polynomials with scalar coefficients that arise in many
state-of-the-art algorithms based on polynomial or rational
approximants, for example, those for computing transcendental
matrix functions. We derive a mixed-precision version of the
Paterson--Stockmeyer method that can be faster and use less
memory than its fixed-precision counterpart while delivering the
same level of accuracy.
