Table/categorical arrays and the <undefined> category
조회 수: 11(최근 30일)
I create a table with different data. Some of the data I set as categorical arrays as such:
table.field = categorical(table.field);
This works fine. When there are NaNs or empty strings within table.field matlab automatically assigns '<undefined>' to those. Also not a problem. However, when I do a unique on them, each '<undefined>' is seen as unique instead of the same. The only way I see around this is to do something like:
table.field(isundefined(table.field)) = 'None';
That seems like a hack. Surely is must be possible to specify what the undefined "label" is in the syntax call?
Hope I'm missing something, Regards, Phil
