i am having trouble with handling polygons with the polybool function. In some cases i get an error that my polygons are invalid, although they look fine in my opinion. Furthermore the calculation of the intersection (same two polygons) does not give the right result. I have added the files with the coordinates of the polygons that cause trouble and the result of the intersection, which has an error in the upper part of the polygons. I hope someone has a solution to this problem.
Thanks in advance
--------------- I'm sorry, i added the files now.

Daniel - the files have not been attached. After choosing the file, make sure you press the Attach File button.

Errors like these can easily arise from small defects in the topology of the input polygons. The MATLAB polyshape class (with methods including intersect, subtract, etc.) is available in R2017b and later and is recommended over polybool. polyshape includes automated data correction/clean-up by default. (See the 'Simplify' name-value option.)
