I need to know the size of each cell based on the following code:
ARRAY = randi(20,20,2);
for i = 1:length(ARRAY)
find_fcn1{i,:} = find(ARRAY(:,1)==(ARRAY(i,1) + 1));
find_fcn2{i,:} = find(ARRAY(:,2)==(ARRAY(i,2) + 1));
end
if lenght('of any cell in find_fcn1' >= 3) || lenght('of any cell in find_fcn2' >= 3)
'do something'
else
'do something'
end
I tried using cellfun but it doesn't work because I generate another array.
Thanks in advance.

G1=findgroups(ARRAY(:,1));
G2=findgroups(ARRAY(:,2));
H1=histcounts(G1,1:max(G1)+1);
H2=histcounts(G2,1:max(G2)+1);
if any(H1>=3) || any(H2>=3)
%do something
else
%do something else
end

"doesn't work" does not allow to understand, what the problem is. Please post the code you have tried and explain, what is not working as expected.
ARRAY = randi(20,20,2);
for i = 1:length(ARRAY)
find_fcn1{i,:} = find(ARRAY(:,1)==(ARRAY(i,1) + 1));
find_fcn2{i,:} = find(ARRAY(:,2)==(ARRAY(i,2) + 1));
end
ge3_fcn1 = cellfun(find_fcn1, 'length') >= 3;
ge3_fcn2 = cellfun(find_fcn2, 'length') >= 3;
match = find(ge3_fcn1 & ge3_fcn2)
Then maybe you need a for loop, not an if condition.
