What are the meaning of row 6 and 7 in the decomposed geometry matrix in matlab R2013b?

Hi, I am using the command DL=decsg(GD,SF,NS) to decompose the solid objects. In previous versions of PDE toolbox, the rows 6 and 7 of the resultant matrix DL used to be the left/right side of geom element. However, the version 2013b has changed this issue and I have not found documentation about it in order to figure out the new meaning of those rows.

Hi,

There were no changes to the decomposed geometry matrix in PDE Toolbox for the R2013b release. This documentation page is correct for that release:

What makes you think there has been a change?
