plotting polygons in matlab

To plot a polygon in Matlab you will need to have the coordinates of its vertices. You can create a vector with the x-coordinates of the vertices and another vector with the y-coordinates of the vertices. Then, use the fill function to plot the polygon. Here is an example code:

main.m
x = [0 3 3 0]; % x-coordinates of vertices
y = [0 0 2 3]; % y-coordinates of vertices

fill(x,y,'r') % plot red polygon
axis equal % set equal aspect ratio

In this example, x and y contain the coordinates of a square-shaped polygon. The fill function is used to plot the polygon and the color is set to red using the 'r' argument. The axis equal command is used to set the aspect ratio of the plot to be equal in both directions.

You can add more vertices to create more complex polygons by adding more coordinates to the x and y vectors.
