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!
