Matrix exponential - MATLAB expm - MathWorks
www.mathworks.com › help › matlabY = expm (X) computes the matrix exponential of X. 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.

Matrix exponential - Wikipedia
https://en.wikipedia.org/wiki/Matrix_exponentialIn mathematics, the matrix exponential is a matrix function on square matrices analogous to the ordinary exponential function. It is used to solve systems of linear differential equations. In the theory of Lie groups, the matrix exponential gives the connection between a matrix Lie algebra and the corresponding Lie group. Let X be an n×n real or complex matrix. The exponential of X, denoted by e or exp(X), is the n×n m…
