@eloise  A graph in polar coordinates can be built using the polarplot function, it takes an angle as the first argument, and a radius as the second. Example:

1
2
3
theta = linspace(0,2*pi);
r = cos(theta).^2;
polarplot(theta, r)

In Matlab, you can create a polar plot using the "polar" function. This function creates a polar coordinate plot of the angle theta versus the radius r. The basic syntax for creating a polar plot is:

1
polar(theta, r)


Where "theta" is a vector of angle values (in radians) and "r" is a vector of corresponding radius values.


Example:

1
2
3
theta = 0:0.01:2*pi;
r = sin(2*theta);
polar(theta,r)


This will create a polar plot of a sine wave with frequency 2.


You can also customize the appearance of the plot by using various optional input arguments and properties of the polar function. For example, you can change the line style, color, and width of the plotted data, add grid lines and labels, etc.
