I am new to Matlab and I am having trouble with all of the f

I am new to Matlab and I am having trouble with all of the following (I have no idea how to use these functions properly)

2. Read in the lines of a text file, e.g. your HW1 submission, using the fgetl function. Store the lines ofthis file in a cell array. Useful functions: for, fopen, fgetl.

3. Parse your stored lines of text into their constituent words using the strtok function. Store all of the words in the entire document in a cell array with one word per index.

4. Create a lexicon consisting of all of the unique words in the document. Useful function: unique.

5. Create a column vector representing how many times each lexicon word occurs in the document; Thisis a word vector representation for the document. Useful function: zeros.

Solution

clc;
clear all;
% Read Data From Text File and Create a Cell arrray to store it.
fid = fopen(\'text1.log\'); % Open the file from which you need to read
tline = fgets(fid); %open file handles
i=1;
while ischar(tline) % Reading each line from text file
data_line(i)={tline}; % storing each line into a cell
tline = fgets(fid); % Read next line
i=i+1;
end
fclose(fid); % close file

% Split sentences into words
j=1;
for i=1:size(data_line,2)
remain=data_line(i);
for k = 1:numel(strsplit(char(remain(1))))-1; % total number of words
[words(j), remain] = strtok(remain); % find a word from the text line
j=j+1;
end
end

% Find out the unique words in the word array
[unique_words,a,b]=unique(words); % find out all the unique words
% Findout Frequency of Occurance of a word
for i=1:numel(a)
final_occurance_mat(i,1)=unique_words(i);
final_occurance_mat(i,2)={sum(b==i)}; % calcualtion of frequency of occurance
end
disp(final_occurance_mat);
