How can I select the common value from table?

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!
