Comparing cell with criteria

Hello! I have cell matrix "Spfcfef" (120x2) as attached and would like to produce 3 outputs.

1) numbers 1-9, that did not appear in either columns, by rows. The result should be a 120 x 1 cell.

2) numbers that appeared in column 1, but not in column 2

Is there a function in matlab that I may use to compare between columns/code with? Many thanks! :)

Have you considered using ismember ? At the bottom of every function's documentation page is a section entitled "See Also", which contains a list of related functions, you can find several functions that would help do what you want.

I did, but I'm not certain how to include Q1 into the code. still learning, am a beginner~

Answer 1

[Stephen23]

out1 = cellfun(@(l,r) setdiff(1:9,[l,r]), Spfcfef(:,1), Spfcfef(:,2), 'Uni',0);
out2 = cellfun(@(l,r) setdiff(l,r),       Spfcfef(:,1), Spfcfef(:,2), 'Uni',0);
