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. exampleEx...
MATLAB Online에서 열기 I am currently trying to solve a matrix exponential of a matrix that has the form of [a 0 b 0] [0 c 0 d] [e 0 f g] [0 h i j] This is obviously not symmetry, and I am very sure this is hard to solve. ...
MATLAB Online에서 열기 다운로드 This method is based on expanding the exponential function on the negative real axis into a rational Chebyshev series. Calling rcexpmv(A,v) returns an approximation to expm(A)*v, i.e., the action of the matrix exponential of A onto a vector...

The paper deals with six approaches how to determine a derivative of the matrix exponential function in the Matlab language environment. Namely, a Taylor series expansion, an augmented matrix utilization, an eigenvalues decomposition, a Laplace transform approach, a convolution integral evaluation and a...
