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 matrix exponential, we get that eAt= L 1[(sI A) 1]: We did an exercise on this during the exercise session. Partial fractional expansion was used in order to get the expressions \on standard form", which can then be found in a table over the Laplace transform in order to get the expression for the matrix exponential. This MATLAB function computes the matrix exponential of X. [4] Moler, C. B. and C. F.

Some of the more computationally useful methods are surveyed in [ ] In principle, the matrix exponential could be computed in many ways and many different methods to calculate matrix exponential [ ,9]. "The matrix exponential is a matrix function on square matrices analogous to the ordinary exponential function." By the way, you know, nowadays, we are not back 50 years, the exponential matrix has the same status on, say, a Matlab or Maple or Mathematica, as the ordinary exponential function does. It is just a command you type in. You type in your matrix. Note that that the above differential equation is a linear, first order equation with constant coefficients, so is simply solved using a matrix exponential. However, if the matrix A was a function of x, then analytic solutions become hard, but the numerical code stays the same.

Although it is not computed this way, if X has a full set of eigenvectors V with corresponding eigenvalues D, then [V,D] = eig (X) and expm (X) = V*diag (exp (diag (D)))/V Use exp for the element-by-element exponential.
