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 R = expm (A) computes the matrix exponential of the square matrix A. The matrix exponential is something Matlab has. So Octave implemented it.

Computing the matrix exponential. Finding reliable and accurate methods to compute the matrix exponential is difficult, and this is still a topic of considerable current research in mathematics and numerical analysis. Matlab, GNU Octave, and SciPy all use the Padé approximant.

Further, we show for each matrix in the set an approximation to the In fact we will need only the special case of the theorem with l = 0. We denote by In the n × n identity matrix and use MATLAB subscripting notation. Theorem 2.1. Do you know what a matrix exponential is, and how it can be used to solve a system of linear, constant coefficient first order equations? If not, then We'll work with exponential regression in a curve fitting in Matlab.

= I + A+ 1 2! A2 + 1 3! A3 + It is not difﬁcult to show that this sum converges for all complex matrices A of any ﬁnite dimension. 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.
