I'm looking for a detailed MATLAB code with explainations.

Thanks!

Complex Numbers: The following Problem can be solved using complex numbers. In the circuit below 2 12 2cos(t) cos(t) mesh analysis can be used to determine the value of the currents and I. After applying Mesh analysis, the following equations are obtained. -(Aj)/1-(2 + 45M2 = 4L0 1. Determine I in r iy and polar form by: (a) Solving the equations by hand (b) Using Matlab to solve for the unknowns To solve the equations by hand, write the systern of equation in the AI = b, then use Gauss elimination method to solve them. You can use the following steps: .Multiply the first row by the conjugate of a11-(3+4j); "by doing this you should get 25 as the new coefficient of I .Repeat the previous step on the second equation, " multiply it by its conjugate which is 4j . Now the coefficients auand a2iare real numbers so you can eliminate azi then use back subst it ut ion to solve for 11and 12. To solve the equations using Matlab Use 1 = Alb . Use Cramer's rule to solve for I and I2 2. Use Matlab to find the real and imaginary part of z and the magnit ude and the argument of z where (3+3i) (4+3i) 3. Write a Matlab program that returns the n roots of a complex number. The function should have z and n as inputs and returs y as the output
