Hubert Matrices

c) The famous Hubert matrices are given by Hij= 1/(i +j - 1). The n x n Hilbert matrix Hn is easily produced in MATLAB using hilb(n). Assume the true solution of H,x = b for a given n is x = [1.. .. , 1]^T. Hence the righthand side b is simply the row sums of H, and b is easily computed in MATLAB using b=sum(hilb(n) 9’. Use your ...continues

Triangular Factorization : Kirchoff's Voltage Law

4. Kirchhoff’s voltage law says that the sum of the voltage drops around any closed path in the network in a given direction is zero. When this principle is applied to the circuit shown in Figure 3.5, we obtain the following linear system of equations: (R1+R3+R4)I1+ R3I2+ R4I3=E1 (1) R311 + (R2 + R3 + R5)12 — R513 = R411 — R5 ...continues
