function "polytope"

[Oyak1]

Dear MTEX team,
my system administrator recently updgraded my MATLAB version from R2011a to R2011b. Today I ran an old script that ususally worked with MTEX3.0. However, there was a problem with the function "polytope":

DATA(i) = polytope(grains(i));
XYdata = get(DATA(i),'xy');

"Undefined function 'polytope' for input arguments of type 'grain'."

The variable 'grains' is previously created using an MTEX grain reconstruction. I usually used that code to extract the xy-coordinates of grain polygones. Can you give me a hint how to modify to code to make it work again with MTEX3.0 in connection with MATLAB R2011b?

Sorry to bother you with questions about ancient versions...

Thanks for your help!
Oyak

Hi guess the easiest way for you would be to ask your system administrator to downgrade to Matlab 2011a.
The other option is to update Matlab to something more recent - maybe 2020b and update MTEX to 5.6.
This is much work I know. But believe me its worth.

Ralf.

Okay, you are probably right. I will start updating my code. Does MTEX 5.6 also work with MTALAB R2015a? This is the freshest version I have available.

You might try but I'm afraid you need something like 2016b - this is the oldest I'm able to check.

Dear Oyak A student license for matlad costs 100 dollars, I am fully aware that in many places this is a lot of money, but you may want to have a look here https://www.mathworks.com/store/link/products/student/SV?s_tid=ac_buy_sv_but1 All the best Luiz Luiz F.
