You are to write a MATLAB function to find the cube root of a complex number. In general, a complex number z is represented as where z1 and z2 are real numbers and i is the imaginary unit. In MATLAB (or Octave), you can compose z out of x and y from the statement z = complex (21, 22) and recover z1 and z2 from z using z1 = real(z), z2 = imag( z) Given the complex number a = a1 +1a2, we are looking for a root of where is described in (1). You are to use this function to compute the cube root of a using Newton's method for two variables To do that, we represent the complex numbers z and a as vectors with two real components. That is the vectors 2 0 2 represent in (1) and a = a1 + 1a2 Then we write f(z) as a function of the two real numbers z1 and z2 parameterized by the two real numbers a1 and a2. Equation (2) my be written f(z; a)-g1 (21, 22; a) + ig2 (,22; a) = 0 where g1(-) and g2 are real valued functions. For f(z) to be zero, both 91(21, 22 and g2(21,22) must be zero since the real and imaginary parts separate. If we let 91 21, 22; a 92(21, 22; a) You are to write a MATLAB function to find the cube root of a complex number.
