In this case, the evaluation of MatrixExp1 [A] often requires considerably less CPU time than the evaluation of MatrixExp [A]. Mathematica has a couple of options to determine a fundamental matrix. It has a build-in command MatrixExp [A t] that determined a fundamental matrix for any square matrix A. Another way to find the fundamental matrix is to use two lines approach: {roots,vectors} = Eigensystem [A] With the numerical matrix exponential. U = MatrixExp[-I*B // N]; the commutator vanishes to numerical precision, A.U - U.A // Norm 8.32424*10^-16.

In this case, the evaluation of MatrixExp1 [A] often requires considerably less CPU time than the evaluation of MatrixExp [A]. I've been doing some calcultations on mathematica which involve exponential of matrices.

Taylor series expansion of exponential functions and the combinations of exponential functions and logarithmic functions or trigonometric functions. Notes on the matrix exponential Erik Wahlén erik.wahlen@math.lu.se ebruaryF 14, 2012 1 Introduction The purpose of these notes is to describe how one can compute the matrix exponential eA when A is not diagonalisable. This is done in escThl by transforming A into Jordan normal form. As we will see here, it is not necessary to go this far. Use the matrix exponential to solve The characteristic polynomial is . You can check that there is only one independent eigenvector, so I can't solve the system by diagonalizing.
