Dear sir/madam,
I am working on geometric shapes. I need to plot geometric shapes like square, rectangle, triangle etc... in matlab. How could I do this in matlab? Looking forward to hearing from you soon.
Thanking you, BSD

Consider also patch()
rectangle() can be used to plot squares, rectangles, ellipses, and circles.

You can just give the coordinates for each vertex, e.g., for square
plot([0 1 1 0 0],[0 0 1 1 0])
If you don't want the axes, you can do
axis off
If you want to be fancy, you can wrap the above code in a function and take the width as the input and then calculate the vertex coordinates inside the function.

Hello,
You might want to have a look at geom2d on the file exchange.

hello brother, you can use GeoGebra app and copy the coordinate of your shape from GeoGebra to matlab one by one.

If you're using release R2017b or later, use the polyshape function.
