This need comes up in DNA analysis, where the 3-base reading frame for a codon (three letter sequence that could be either T, C, A or G) can begin at any point in the sequence. The identified unique n-gram sequences should be sorted alphabetically. If there are no n-grams, or if the inputs are not of the cormect datatype, then outputs should be empty. For example >uniquegrams,count] nGramFrequency (s,lengthnGram) 1x6 string array "AAC"ACG"ACT""CTG" GAA"TGA count = The unique 3-grams are "AAC once "ACG" "ACT"CTG" "GAA" TGA", with the exception of AAC that appears twice, all appear >> s-"AACTGAACG" ; lengthnGram=10;[uniquegrams, count): nGran Frequency(s, lengthnGram) [l count = [l Your Function Save Reset E MATLAB Documentation 1 function [uniqueGrams, countGrams] nGramFrequency (instring,lengthnGram) % Your code goes here % s end Code to call your function C Reset 2 [uniquegrams,count] - nGramFrequency (s,lengthnGram)
