Hello every one
I have this cell
S=
2
1 2 3
1 2 5
1 5
and the data like this
T=
1 2 4 5
2 3 5
1 2 4 5
1 2 3 5
each line from S I count it appearance in T as well as its index
I obtained this
vect=[ 3 1 3 4]
index=[1 2 3 4]
I sorted them and I obtained:
vect=[4 3 3 1 ]
index=[4 1 3 2]
So,
My issue is:
I want to remove the common value exist in almost all value of S
for example
value=2;
exist in all most of S, then I removed it
How Can I do thant?
thank you

Hi Mira,
To find the most frequently appearing element in all rows of your matrix, you can use the code below -
% Define the 3D matrix as a cell array to handle different row lengths
matrix = {[2], [1 2 3], [1 2 5], [1 5]};
% Concatenate all elements into a single array
allElements = [matrix{:}];
% Find the unique elements and their counts
[uniqueElements, ~, indices] = unique(allElements);
counts = accumarray(indices, 1);
% Find the element with the maximum count
[maxCount, maxIndex] = max(counts);
mostFrequentElement = uniqueElements(maxIndex);
% Display the result
fprintf('The most frequently occurring element is: %d\n', mostFrequentElement);
Hope this helps!
