The matrix exponential formula for real equal eigenvalues: (I denoting the n ×n identity matrix) converges to an n ×n matrix denoted by exp(A). One can then prove (see [3]) that exp(tA) = A exp(tA) = exp(tA)A. (1) (All derivatives will be with respect to a real parameter t.) The question is whether the chain rule (1) extends to more general matrix exponential functions than just exp(tA). For example, if you really mean that [s^x] is the matrix A (s) such that A (s)y=sXy, then (exp (-tA (s)))_t=-A (s)exp (-tA (s)). Or you could use the chain rule if you regard A (s) as a matrix with The Matrix Exponential For each n n complex matrix A, define the exponential of A to be the matrix (1) eA = ¥ å k=0 Ak k!

The shortest form of the solution uses the matrix exponential y = e At y(0). The matrix e At has eigenvalues e λt and the eigenvectors of A. Computing the Fréchet derivative of the matrix exponential, with an application to condition number estimation. AH Al-Mohy, NJ Higham.

If the derivatives are taken with respect to the entries of the matrix argument, the first and second linearizations can be obtained directly. The Fréchet derivative of the matrix exponential describes the first-order sensitivity of $e^A$ to perturbations in $A$ and its norm determines a condition number for $e^A$.

The exponential of A is defined via its Taylor series, eA = I + X∞ n=1 An n!, (1) where I is the n×n identity matrix. The radius of convergence of the above series is infinite. Consequently, eq.
