If you are creating an interactive rectangle for use with ROI, then you might prefer drawrectangle https://www.mathworks.com/help/images/ref/drawrectangle.html
If you have already determined the coordinates of the rectangle and want to draw it to the display, see rectangle()
If you need to create a rectangle inside an array, such as if you are drawing on top of an image array, then see insertShape() from the Computer Vision Toolbox
