I'm trying to create a 2-D domain for my PDE model. I've been using MATLAB's examples for Partial Differential Equation Toolbox as references, but none of them construct their own geometry.
What I'm trying to create is a rectangular domain which has the following specifications. X-domain: [-117.25, -117.0] and Y-domain: [32.55,33.03]
How could I do this to input into the geometryFromEdges() function?
Thank you!

What about the doc example isn't sufficient for you? It literally creates a rectangle.

Thank you so much!
Could you explain to me how you created R? I'm not sure what the values represent.

I used the doc example opened with below and modified it to suit (i.e. didn't use the circle), but the definition of R in decsg is here: https://www.mathworks.com/help/releases/R2022a/pde/ug/decsg.html#bu_fft3-gd
openExample('pde/GeometryFromDecomposedSolidGeometryExample')
