Sep 26, 2012 Two of the algorithms described here are available as MATLAB codes Keywords: matrix exponential, Maxwell's equations, Krylov subspace.

We’re going to experiment with three different methods to cope with our exponential regression. The first method is a classical computation using known formulas. The second method deals with strategic optimization techniques and gives another example of the simplex method implemented by the Nelder-Mead algorithm used in the Matlab function fminsearch.

Compute the matrix exponential for the 2-by-2 matrix and simplify the result. syms x A = [0 x; -x 0]; simplify(expm(A)) ans = [ cos(x), sin(x)] [ -sin(x), cos(x)] The matrix exponential is a special case of raising a scalar to a matrix power. The base for a matrix exponential is Euler's number e = exp (1). e = exp (1); e^A.

The expm function is built-in, but it uses the Padé approximation with scaling and squaring algorithm where τ is the sampling period. MATLAB Control System Toolbox: c2d and d2c. MIMS. Nick Higham. Matrix Exponential. 12 / Like many MATLAB functions, the exp function operates element-wise when applied to arrays. For further details, please refer to the e^x and expm(m) represent e raise to the matrix x .

We can also plot the functions which we have computed using the ‘plot’ expression, which allows us to visually interpret our function.
