The Fréchet derivativeof a matrix functionis used in a variety of applications and several algorithms are available for computing it. We define a condition number for the Fréchet derivative and derive upper and lower bounds for it that differ by at most a factor. For a wide class of functions we derive an algorithm for estimating the 1-norm condition number that requiresflops givenflops algorithms for evaluatingand; in practice it produces estimates correct to within a factor. Numerical experiments show the new algorithm to be much more reliable than a previous heuristic estimate of conditioning.
