lets say I have to read a text file, then take out specific words and create a program that counts the number of words taken out, how would one do that?

Best Answer

fid = fopen(filename);
T = textscan(fid, '%s');
T = T{1};
fclose(fid);
idx = strcmp(T, 'word_to_take_out');
Nword_to_take_out = nnz(idx);
T(idx) = []; % remove from T

This works

fullFileName = fullfile(pwd, 'MATBIP_04_Channel_1.txt');
% Open the file for reading in text mode.
fileID = fopen(fullFileName, 'rt');
% Read the first line of the file, but don't use this header line.
textLine = fgetl(fileID);
% Read the second line of the file.
textLine = fgetl(fileID);
lineCount = 0;
while ischar(textLine)
	lineCount = lineCount + 1;
	% Print out what line we're operating on.
	fprintf('%s\n', textLine);
	% Get rid of quotes
	textLine(textLine == '''') = [];
        % Parse string into numbers.
	numbers(lineCount, 1:3) = sscanf(textLine, '%f	%f	%f');
	% Read the next line.
	textLine = fgetl(fileID);
end
% All done reading all lines, so close the file.
fclose(fileID);
