+    # (https://github.com/matlab-actions/setup-matlab/issues/18#issuecomment-1006990188). This is in version
+    # 1.1.0 of the action, and only provides the bare Matlab and Simulink products with no toolboxes.

+    # Lock the Windows version to 2019 because the 2022 image doesn't include a supported compiler for the
