Using intersect to assign a classification
显示 更早的评论
Hi there!
I've created a classification matrix and have used intersect to find the common cell, but the problem is that I want the information in the cell next to it.
Example:
US-Goo US-Ha1 US-Ha2
GRA DBF ENF
What I have:
a=length(landclass)
IGBPclass=intersect(sitename, landclass)
IGBPclass='US-Ha1'
Ideally I want IGBPclass to be the second 3 letter classification.
Thanks!

Show us sitename and landclass. Show the result you are getting. Show the result that you want. Why do you overwrite IGBPclass in the 3rd line of code,
IGBPclass='US-Ha1'

The third line is the output of the intersect function.
That's very confusing since we cannot distinguish it from other lines of code. This is how you should show contents of variables to the public,
>> landclass, sitename
landclass =
'US-Goo' 'US-Ha1' 'US-Ha2'
'GRA' 'DBF' 'ENF'
sitename =
US-Ha1
If the above is the form your data is in, I suspect you are trying to do this:
>> logicalIndex=ismember(landclass(1,:),sitename);
>> IGBPclass=landclass{2,logicalIndex}
IGBPclass =
DBF

I don't fully understand what you are trying to do. However, if you read
doc intersect
you will see that you can call that command with more than one output. The second and third outputs are the indices for the elements that are in the intersection of the two sets. Maybe you can use those indices to do what you want.
