I have A
A={[1,2;4,5;8,9],[1,2,3;4,5,6;1,4,5;2,4,5],[3,4,5,6;1,2,3,4;8,9,0,8;3,4,5,6]}
B={[1;3],[2;4],[2]}
I want to remove B rows from A.
I use this code, but it has a error
cellfun(@(m,n)m(n,:)=[],A,B,'uni',0);
result should be
A={[4,5],[1,2,3;1,4,5],[3,4,5,6;8,9,0,8;3,4,5,6]}

You could use cellfun like this:
>> F = @(m,x) m(setdiff(1:size(m,1),x),:);
>> C = cellfun(F,A,B,'uni',0);
>> C{:}
ans =
4 5
ans =
1 2 3
1 4 5
ans =
3 4 5 6
8 9 0 8
3 4 5 6
or use a simple for loop:
>> for k = 1:numel(A), A{k}(B{k},:) = []; end
>> A{:}
ans =
4 5
ans =
1 2 3
1 4 5
ans =
3 4 5 6
8 9 0 8
3 4 5 6
