MATLAB: Find similar elements in a matrix

similar numbers

My question is that , I have a matrix, I want to know which element from which columns are similar, which number is the most repeated number for example
X=[1  2  3  3  3
45  7  4  4  4
70  8  5  5  5
88  9  11  11  11
170  205  13  13  13
172  220  14  23  24
194  222  24  24  41
196  224  41  152  67
200  539  62  183  68
250  540  67  184  71
251  1415  68  185  148
255  1426  71  187  151
]
for example here 3 (repeated in columns 3,4 and5) the same for 4, 5, 1, 13
and the most repeated numbers are 3,4,5,11, and 13

Best Answer

[h1 h2] =hist(X(:),unique(X));
h3 = unique(h1);
h3 = h3(end:-1:1);
for k=1:length(h3)
  disp(['There is ' num2str(h3(k)) ': [ ' num2str(h2(h1==h3(k))')  ' ]'])
end
