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.

Matlab function: expm – Matrix exponential. linear algebra mathematics MATLAB. expm. Matrix exponential. Introduced before R2006a. Description. Y = expm(X) computes
rated in popular computing packages such as Matlab (expm) and Mathematica (MatrixExp) in combination with Pad e approximants [2,8,10]. Speci cally, for a given matrix A2C N, the scaling and squaring technique is based on the key property (1.1) eA= eA=2s 2s; s2N: The exponential eA=2s is then replaced by a rational approximation r m(A=2s), View MATLAB Command.
It is extremely useful for the students taking a course on Numerical Analysis, as it will help them to compare and analyse the data given in their text-books.
I work a lot with R and Armadillo via the RcppArmadillo package (for which I'm a co-author). This MATLAB function generates a random number from the exponential distribution with mean mu. then r is a square matrix of size sz1-by-sz1. Evaluation of Matrix Exponential Using Fundamental Matrix: In the case A is not diagonalizable, one approach to obtain matrix exponential is to use Jordan forms. Here, we use another approach. We have already learned how to solve the initial value problem d~x dt = A~x; ~x(0) = ~x0: This MATLAB function computes A to the B power and returns the result in C. If A is a 2-by-2 or larger matrix and B is Inf or -Inf, 比较两种指数运算结果.

The Matlab function expm(A) computes the matrix exponential eA. In contrast, exp(A) computes the elementwise exponential of the matrix A, which is usually not what you want. Time-invariant autonomous linear dynamical system Suppose ˙x = Ax, with A ∈ Rn×n (and constant).
