Exponent of matrix
Web1 Properties of the Matrix Exponential Let A be a real or complex n×n matrix. The exponential of A is defined via its Taylor series, eA = I + X∞ n=1 An n!, (1) where I is the n×n identity matrix. The radius of convergence of the above series is infinite. Consequently, eq. (1) converges for all matrices A. In these notes, we discuss a ... WebYou could multiply this out, but, actually, the exponential matrix is often a pain in the neck to compute, and is often more useful as a symbolic device. Just like ex, in fact! [5] The exponential law I claim that eA(t+s) = eAteAs This is a consequence of \time invariance." We have to see that both sides are equal after multiplying by an ...
