But we will not prove this here. If A is a 1 t1 matrix [t], then eA = [e ], by the The matrix exponential is something Matlab has. So Octave implemented it. So other Free Software projects looked at what Octave has and reimplemented it by borrowing this implementation.
MatrixExp[m, v] gives the matrix exponential of m applied to the vector v. In 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 … View MATLAB Command. Compute and compare the exponential of A with the matrix exponential of A.

Y = 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.

MIMS Nick Higham Matrix Exponential 12 / 39. The matrix exponential can be successfully used for solving systems of differential equations. Consider a system of linear homogeneous equations, which in matrix form can be written as follows: \[\mathbf{X}’\left( t \right) = A\mathbf{X}\left( t \right).\] The general solution of this system is represented in terms of the matrix exponential as

What is the difference between Matrix Learn more about second order matrix exponential
This submission contains two functions for computing EXPM (t*A)*b without explicitly forming EXPM (t*A), where A is an n-by-n matrix and b is an n-by-1 vector. This is the problem of computing the action of the matrix exponential on a vector. EXPMV (t,A,B, computes EXPM (t*A)*B, while EXPMV_TSPAN (A,b,t0,tmax,q) computes EXPM (t*A)*b for q+1 >= 2 equally spaced values of T between T0 and TMAX. If you want to compute the matrix exponential e^(A t), where A is a n x n square matrix and t is a variable, and you DO NOT want to do simply do the by-element exponential, i.e., you want to compute the equivalent of the inverse Laplace of s*eye(n)-A, which is important in state-space analysis of linear systems, you want to use expm(A*t), not exp(A*t).
