PDEToolbox + Passing own parameters to the function defining geometry

I'm using PDE toolbox to solve some 2D PDE. The geometry is generated by function which is standarized and should have two parameters:

 function [x,y]= @geometryFunction(bs,s)

and which is then passed to geometryFromEdges function:

 geometryFromEdges(pdemodel,@geometryFunction) ;

I would like to pass additional parameters to the geometryFunction to have it more robust. The only way I can achieve it now is by using global variables (in the main file and in geometryFunction), which is not very convenient and elegant solution. Is there any other way for passing own parameters to the function that defines geometry?

Shame on me. Thanks for recalling me this topic.
