how to calculate frequency in 3 different text?

I could calculate frequency in one word but how to compare it to 3 text?

words is my text wchi was split in strt

[wordsu, idx, idxU] = unique( words ) ;

counts = accumarray( idxU, 1 ) ;

[~, S] = sort( counts, 'descend' ) ;

words_us = wordsu(S) ;

counts_s = counts(S)

result = [words_us, num2cell( counts_s )]

I mean the same word in the different text something like this

word text1 freq text2 freq text3 freq

and 5 6 5

the 4 6 3

..
