Creating a Function that acts as a counter for certain string

Okay, I am trying to create a function that reads a txt. file then for every certain string counts it as one until it reaches 10. Then the 10th string is taken and placed in an array. Can anyone help me?

Hey @Frandy , In MATLAB, you can create a function to read a text file, count occurrences of a specific string, and collect every 10th occurrence into an array. Here's an example function that does this:

function resultArray = collectEveryTenthOccurrence(filename, searchString)

% Initialize the counter and the result array

occurrences = 0;

resultArray = {};

% Open the text file for reading

fid = fopen(filename, 'rt');

if fid == -1

error('File cannot be opened: %s', filename);

end

% Read the file line by line

while ~feof(fid)

line = fgetl(fid);

words = strsplit(line); % Split the line into words

for i = 1:length(words)

word = words{i};

% Check if the word matches the search string

if strcmp(word, searchString)

occurrences = occurrences + 1;

% If the 10th occurrence, add to the result array

if mod(occurrences, 10) == 0

resultArray{end+1} = word;

end

end

end

end

% Close the file

fclose(fid);

end

To use this function, you would call it with the filename and the search string as arguments, like so:

collectedWords = collectEveryTenthOccurrence('sample.txt', 'example');

disp(collectedWords);

Hope it helps!
