Abstract

Let a matrix be A2C(n;n) and we want to calculate its exponential matrix etA knowing only the eigenvalues ​​of A, it is not necessary to know the respective eigenvectors. The approach presented is the relationship between the exponential matrix with the matrices with Vandermon deV sources. This approach and the resulting methods are very simple and can be considered as an alternative to using Jordan's canonical form. The analysis of the algorithms for inversion of the matrix V, as well as the matrix representation of V1, are of independent interest in many other applications.
