One of the properties is that $e^{{\bf A}+{\bf B}}\neq e^{\bf A}e^{\bf B}$ unless ${\bf AB}$$={\bf BA}$. The The above theorem says that if \(Mx=0\), then the vector \(x\) is orthogonal to every vector in the row space of \(M\). For example, the graph pictured above would have the following matrix, where \(m^{i}_{j}\) indicates the number of edges between the vertices labeled \(i\) and \(j\): \[ }D^{k}_{j}) \nonumber\], with regard to our example we find, \(h=1, \lambda_{1}=0, P_{1}=I, m_{1}=2, D_{1}=A\) so, Let us consider a slightly bigger example, if, \[A = \begin{pmatrix} {1}&{1}&{0}\\ {0}&{1}&{0}\\ {0}&{0}&{2} \end{pmatrix} \nonumber\], and so \(\lambda_{1} = 1\) and \(\lambda_{2} = 2\) while, \[P_{1} = \begin{pmatrix} {1}&{0}&{0}\\ {0}&{1}&{0}\\ {0}&{0}&{0} \end{pmatrix} \nonumber\], \[D_{1} = \begin{pmatrix} {0}&{1}&{0}\\ {0}&{0}&{0}\\ {0}&{0}&{0} \end{pmatrix} \nonumber\], \[P_{2} = \begin{pmatrix} {0}&{0}&{0}\\ {0}&{0}&{0}\\ {0}&{0}&{1} \end{pmatrix} \nonumber\], \[e^{At} = e^{t}(P_{1}+tD_{1})+e^{2t}P_{2} \nonumber\], \[\begin{pmatrix} {e^t}&{te^t}&{0}\\ {0}&{e^t}&{0}\\ {0}&{0}&{e^{2t}} \end{pmatrix} \nonumber\]. \hline If \(A\) is a zero matrix, then \({e^{tA}} = {e^0} = I;\) (\(I\) is the identity matrix); If \(A = I,\) then \({e^{tI}} = {e^t}I;\), If \(A\) has an inverse matrix \({A^{ - 1}},\) then \({e^A}{e^{ - A}} = I;\). $$

In order to exploit it we need to recall that all matrices are almost diagonalizable. The matrix exponential of a diagonal matrix is a diagonal matrix with the diagonal entries exponentiated: If m is diagonalizable with , then : MatrixExp [m] is always invertible, and the inverse is given by MatrixExp [-m]: MatrixExp of a real, antisymmetric matrix is orthogonal: 1 & 2 & 3 \\ \begin{pmatrix} /Rect [85.403 375.313 362.143 386.161] How can I evaluate this exponential equation with natural logarithm $6161.859 = 22000\cdot(1.025^n-1)$?
