Many MATLAB and Toolbox functions require the specification of rectangular regions. Several use "position vectors," specified as [Xmin Ymin Width Height], many others require specification by vertex, [x; y]. For rectangular ROIs, either one defines the other. This submission facilitates easy conversion from position to vertex:
verts = posToVert(posn);
or from vertices to position:
posn = vertToPos(vert);
Simple, but useful.
