Nettet15. des. 2014 · Which is more or less the situation described by Amzoti (he expanded the system of equations as you wanted to do, here we are using matrix exponential with Laplace transform). So: step 1: Write (sI − A). step2: Find (sI − A) − 1, this is a problem of linear algebra actually: finding inverses. You can check this out on a linear algebra book. NettetSolve a linear matrix equation, or system of linear scalar equations. Computes the “exact” solution, x, of the well-determined, i.e., full rank, linear matrix equation ax = b. Parameters: a(…, M, M) array_like Coefficient matrix. b{ (…, M,), (…, M, K)}, array_like Ordinate or “dependent variable” values. Returns: x{ (…, M,), (…, M, K)} ndarray
NettetThus we may construct the following system of linear equations , Solving these equations, we find that both constants A and B equal 1/3. Therefore substituting these values into the general form of these two functions specifies their exact forms, the two functions sought. Using matrix exponentiation [ edit]
