You may use Gmsh to generate unstructured quadrilateral mesh in Matlab.

It's possible to define multi-part geometry in Matlab, and then generate unstructured quadrilateral mesh via Im2mesh (a Matlab package using Gmsh as mesh generator).

Please check these two examples: demo14 demo13

To run demo14, you need to install Matlab mapping toolbox, and download Im2mesh package and Gmsh sofware.
