I have two tables:
So they are different size, and ID's from first columns are the same identificators. I would like to extend the table Selected_Processess, so in 3rd column I'd parameter amount_of_occurences from table Processes(:,2) but just for shared ID's from first columns, so for example for the first 2 rows(only this two are visible and shared ID's between the tables in those screenshots) it would look like:
table = [2 2 6;
15 1 4]
After this, the table should have size 228x3.
I was doing similar thing with strings inside cellarray, and function isamember worked perfectly, but for integers it's different.
Ps. I don't mind changing this data from table to any other form such as cell, etc. as long as it would work as I need.
Thanks in advance for your help :)

I didn't completely follow what you are trying to do, but I'm pretty sure you should be able to use the join command to do what you want.
