MatLAB question. All of part A and B needed.!

Problem 5: Mesh Analysis A student in a circuits class writes mesh equations for the circuit shown below and now must solve for the unknown currents (Ii, 12, I3, and 14). 4.7 3.6 k 12V I1 ^^ 1.1k 13 4.7 k I4 2.2 k 8.1 k 4711 + 3.6(11-12) + 1(11-13) = 0 3.6(12-11) + 212 + 1.1(12-14)--12 1(13-11) + 4.7(13-14) + 8.113 = 9 4.7(14-13) + 1.1(14-12) + 2.214 = 0 (a) Write the equations in matrix form and use MATLAB to solve for all four currents. The units for the currents will be in milliamps (mA)
