To illustrate and quantify ourdiscussion, we compute the matrix exponential by means of an FFT based algorithm. Particularattention is paid to a comparison of

If theta is not. matrix runs well into the hundreds. As a matter of fact, this technique is incorpo- rated in popular computing packages such as Matlab (expm) and Mathematica. In Mathematica there is an distinction between powering elements keep the result exact if the matrix and the exponent is exact. May 25, 2008 Even though I have a Mathematica® command which computes matrix exponentials for me, it's nice to have some idea how I could check a Jun 16, 2020 exponential function for both diagonalizable and defective matrices.

Matrix exponential mathematica

We will write the diagonal approximants as r m(x)=p m(x)/q m(x). Our aim is to choose s, in the initial scaling A ← A/2s, so that the exponential is Is there a way to compute one matrix element of the exponential of a tridiagonal matrix without having to compute the rest of the elements? Motivation: I'm trying to find the first passage time This example shows 3 of the 19 ways to compute the exponential of a matrix. For background on the computation of matrix exponentials, see: Moler, C. and C. Van Loan. "Nineteen dubious ways to compute the exponential of a matrix, twenty-five years later." SIAM Review. Vol. 45, Number 1, 2003, pp. 3-49.
