I found the answer to drawing rotated rectangles using the solution provided here by Y Yoon. However, I am not sure how to integrate curvature to the rectangle at the edges like it can be done in the function rectangle. Any other solution will also be highly appreciated. Thanks in advance.

I created a function to extend the capabilities of Matlab's rectangle() but with these additional features:
  • Position rectangles by their center points rather than by their lower left coordinate.
  • Supports creation of multiple rectangles with independent properties
  • Outputs handles to patch object rather than rectangle
  • Outputs rectangles parameters including vertices
  • Option to rotate rectangles about their centers
See the example file in rectangle2() on the file exchange.

Please download vs 2.0.0 which I just updated.
It fixes some minor potential errors but it also adds a lot of flexibility to set multiple rectangle properties (see example file).
I don't plan for any further updates unless errors are reported. At some point I may get around to figuring out how Matalb creates the curved edges rather than using the rectangle function to create them.
