hand can becometedious. When this is the case, it is often useful to use programs such as Maple and Matlab to solvethe problems. The following is a typical problem of such cases (a) Express the linear system developed by nodal analysis using matrices in the form AX = B,%3D (b) Find the reduced echelon form of the augmented matrix. (c) Find A- using Gauss-Jordan elimination method or Matlab. (d) Solve for in Vn E {s, 1,2.,9}, by using the reduced echelon form of the augmented matrix found in (b), the inverse matrix of A found in (c) and Cramer's rule, and compare between the three methods Note that R = 42, R2 = 22, R3 = 22, R4 = 52,R5 = 52, R6 = 102.
