Hi,
I have a large dataset with over 4 million rows. I do not know all the values of a particular column. There are 2 that I know, and 1-2 others hidden among the 4 million. How can I find the other values so I can split the datasets by values of that column?
Thanks,
Tim

Or more likely in your case, findgroups

findgroups, I believe - just one "print" of each group, divided by number.

[GroupNumber, GroupValues] = findgroups(YourTable.AppropriateColumnName);
Then all of the entries in GroupNumber that == 1 had AppropriateColumnName value the same as GroupValues(1), and all of the entries in GroupNumber == 2 had AppropriateColumnName value the same as GroupValues(2) and so on.
