    I do not fully understand these questions mainly how to do the matlab parts. Some explanation and advise would be appreciated.

    1. If z = −2 + 3j and w = 4 − 5j then using Matlab evaluate
    a) modulus z, argument z, conjugate z, imaginary part of z and finally the real part of z.
    b) Graph z and w on a suitable plot.
    c) Evaluate z+w, z-w, z*w and z/w.
    2. Using the Matlab file ’Solve Eqn’, change the computer code to solve
    a) z
    3 = 1
    b) z
    4 = 1
    c) Provide a brief argument of what results you would expect for the equation z
    8 = 1.
    d) Solve by ’pen and paper’ the equation z
    5 = 1 + j, and check your results with Matlab.

    First you want to define your z and w before proceeding. Then part a can easily be googled for the commands.
