The Exponential of a Matrix. The solution to the exponential growth equation It is natural to ask whether you can solve a constant coefficient linear system in a similar way. If a solution to the system is to have the same form as the growth equation solution, it should look like The first thing I need to do is to make sense of the matrix exponential.

Among the The matrix exponential plays an important role in solving system of linear differential equations. On this page, we will define such an object and show its most important properties. The natural way of defining the exponential of a matrix is to go back to the exponential function exand find a definition which is easy to extend to matrices. Matrix Exponential. Fundamental Matrix Solution.

Equivalently, eAtis the matrix with the same eigenvectors as A but with eigenvalues replaced by e t. especially matrix Exponential .The matrix exponential is a very important subclass of functions of matrices that has been studied extensively in the last 50 years [ ]. The computation of matrix functions has been one of the most challenging problems in numerical linear algebra. Among the Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.

The Matrix Exponential For each n n complex matrix A, deﬁne the exponential of A to be the matrix (1) eA = ¥ å k=0 Ak k! = I + A+ 1 2! A2 + 1 3! A3 + It is not difﬁcult to show that this sum converges for all complex matrices A of any ﬁnite dimension. But we will not prove this here. If A is a 1 t1 matrix [t], then eA = [e ], by the Maclaurin series formula for the function y = et. der gewöhnlichen Exponentialfunktion.

If A is a 1 t1 matrix [t], then eA = [e ], by the The Exponential of a Matrix The solution to the exponential growth equation It is natural to ask whether you can solve a constant coefficient linear system in a similar way. 10.4 Matrix Exponential 505 10.4 Matrix Exponential The problem x′(t) = Ax(t), x(0) = x0 has a unique solution, according to the Picard-Lindel¨of theorem. Solve the problem n times, when x0 equals a column of the identity matrix, where we have de ned the \matrix exponential" of a diagonalizable matrix as: eAt= Xe tX 1 Note that we have de ned the exponential e t of a diagonal matrix to be the diagonal matrix of the e tvalues. Equivalently, eAtis the matrix with the same eigenvectors as A but with eigenvalues replaced by e t. especially matrix Exponential .The matrix exponential is a very important subclass of functions of matrices that has been studied extensively in the last 50 years [ ].
