Problem 13.13. Consider the system of three linear differential equations: xt = 2x1 + 3x2 + 4.13 where the unknowns are the three functions xi(t), x2(t), and 23(t). x'a = 2x2 + 6.13 (a) Write the system in the form x' = Ax, where A is a (3 x 3) matrix. X'z = 2x3 (b) Write A as the sum of two matrices, A=D+U, where D is a diagonal matrix (all of the off-diagonal entries are zero, and the diagonal...

Consider the linear system in three equations and three unknowns: 1) x + 2y + 3z = 6, 2) 2x − 5y − z = 5, 3) −x + 3y + z = −2 . (a) First, identify the matrix A and the vectors x and vector b such that A vector x = vector b. (b) Write this system of equations as an augmented matrix system. (c) Row reduce this augmented matrix system to show that there is exactly...

Let A e Rmxn. The linear system Ax = b can have either: (i) a unique solution, (ii) no solution, or (iii) infinitely many solutions. If A is square and invertible, there is a unique solution, which can be written as x = A-'b. The concept of pseudoinverse seeks to generalise this idea to non-square matrices and to cases (ii) and (iii). Taking case (ii) of an inconsistent linear system, we may solve the normal equations AT Ar = Ab...
