Spectrum mapping theory in Euclidean space was proved with a simple method on the basis of the spectrum mapping theory in functional analysis by making use of the feature that a matrix can be reduced into Jordan.The relation was given between the eigenvalue of matrix exponent and the eigenvalue of the matrix,with an example cited to illustrate the effectiveness of the result.
