Create Boundary Condition Matrix from PDEModel geometry

I am trying to solve a PDE using the PDE toolbox. It is complex and nonlinear, and due to a possible bug

(see http://www.mathworks.com/matlabcentral/answers/296527-solvepde-fails-on-complex-f-coefficient?s_tid=srchtitle)

I need to use the legacy function adaptmesh().

However, adaptmesh() appears to require boundary conditions in the form of a Boundary Condition Matrix, which is not compatible with the current methods (<http://www.mathworks.com/help/pde/ug/steps-to-specify-a-boundary-conditions-object.html)>.

Is there a way to automatically translate the boundary conditions from applyBoundaryCondition() to a Boundary Condition Matrix?

The easiest way to create a boundary matrix is to export it from the PDE app. As far as I know, there is no easy way to transfer a boundary condition from the recommended workflow to the legacy workflow.

You can also write a function to represent boundary conditions, though it is not nearly as nice a syntax as the recommended workflow.

Good luck, and I apologize for the bug.
