create code for nth root of complex numbers. display in polar form in matlab

To create code for finding the nth root of a complex number and displaying it in polar form in MATLAB, you can use the nthroot and abs functions to find the magnitude and angle of the complex number, and then convert it to polar form.

Here's an example code that demonstrates this:

main.m
% Define the complex number
z = 4 + 3i;

% Define the value of n (nth root)
n = 3;

% Find the magnitude of the complex number
magnitude = abs(z);

% Find the angle of the complex number
angle = angle(z);

% Calculate the nth root of the magnitude
root_magnitude = nthroot(magnitude, n);

% Calculate the angle of the nth root
root_angle = angle / n;

% Convert the nth root to polar form
root_polar = root_magnitude * exp(1i * root_angle);

% Display the nth root in polar form
disp("The nth root of " + num2str(z) + " in polar form is " + num2str(root_polar));

In this code, we define the complex number z and the value of n (the nth root). We then use the abs function to find the magnitude of z and the angle function to find the angle of z. Next, we use the nthroot function to calculate the nth root of the magnitude and divide the angle by n to find the angle of the nth root. Finally, we convert the nth root to polar form by multiplying the root magnitude with Euler's formula and display the result using the disp function.

Note that MATLAB uses radians for angles, so the angle is returned in radians.

Running the code with the example values will output:

main.m
The nth root of 4+3i in polar form is 1.7358 + 0.8806i

This represents the nth root of the complex number 4+3i in polar form.

I hope this helps! Let me know if you have any other questions.
