The twelfth root of a matrix

[Arduinol]

Thanks a lot Gribouillis!!!

You're right regarding these 3 matrices : the third line is an absorbing state and will always be the case. So, as you mentioned, I hope this should be easier.
By the way, the output seems a bit odd to me, I would expect the result to be more similar to (I give you an example) :

For Matrix B as :

93,40% 6,00% 0,60%
18,00% 71,90% 10,10%
0,00% 0,00% 100,00%

I should get Matrix A :

99,376864% 0,601245% 0,0218908%
1,803736% 97,222401% 0,9738627%
0% 0% 100%

Have you got a solution to modify the code in order to get the same result?

Thank you so much for your help!

Best Regards,
