Hi,
We have previously used strings for properties of various entries in tables, and have now converted them to categoricals. Before, we could have cat1 and cat2 and we could create a new merged category by concatenating the two:
tab = table;tab.cat1 = {'true','false','false','null'}';tab.cat2 = {'one','one','many','many'}';tab.cat3 = strcat(tab.cat1, tab.cat2);
Is there a similar approach for categoricals? What we do now is converting back and forth from string, but that seems inefficient and slow for large tables.
tab = table;tab.cat1 = categorical({'true','false','false','null'}');tab.cat2 = categorical({'one','one','many','many'}');tab.cat3 = categorical(strcat(cellstr(tab.cat1), cellstr(tab.cat2)));
Instead it would be nice if you could do something like:
tab.cat3 = catcat(tab.cat1, tab.cat2);
