WebFirst we get the frequency table from somewhere (in this case the Huffman object we used to encode the data) and then call decompressData(). The string that results should be equal to the one we compressed in the first place. we can see how this works in more detail in the Playground. See also. Huffman coding at Wikipedia Webcode = huffmanenco(sig,dict) encodes input signal sig using the Huffman codes described by input code dictionary dict. sig can have the form of a vector, cell array, or alphanumeric cell array. If sig is a cell array, it must be either a row or a column.dict is an N-by-2 cell array, where N is the number of distinct possible symbols to encode. on the border colorado springs colorado
