MATLAB: I didnot understand this code i want help stp_w={‘is’,’the’}; f = fopen(‘gg.txt’); I = textscan(f,’%s’,100);% d=I{1}; for(i=1:2) x = strmatch(d(i), stp_w) If x~=1

MATLAB

this is about classify text document

clc; clear all;
stp_w={'is','the'};   % set of strings is and the
f = fopen('gg.txt');   % gg.txt text file is opened 
I = textscan(f,'%s',100);  % the data in the file is scanned, it scans into cells 
d=I{1}; % the first line data from the text file
for(i=1:2) % loop from 1 to 2 
    x = strmatch(d(i), stp_w) % trying to find wheter is/the exists in first line using strmatch(stringmatch)
    If x~=1    % if the word exists, goes inside if
end

f = fopen('gg.txt','r');  % opens text file gg.txt
I = textscan(f,'%s',100); % scans the data into strings in I
d=I{1};    % the first line
for i=1:length(d)   % loop for every data in first line 

    x = strmatch(d(i), stp_w);    % matching each string in d with stp_w
    c=0;     % a constant c = 0, for count 
    if x~=1  % if string is not matching 
        for j=1:length(d) % loop for every data in first line 
            x = strmatch(d(i),d(j) );  % comapring the strings in text file with it selfs
            if x==1     % is string matches 
                c=c+1;  % count increased 
            end   
        end
        feq(i)=c;     % saving ht ecount 
    end
end

MATLAB: Trying to delete lines that start with an alphabet on a text file

Use fopen, fgetl, fclose to read your file into a cell array and discard the lines you don't want. Or if you want to write a new file, use fopen, fprintf, fclose and write as your read:

fidi = fopen('somefile.txt', 'rt');
fido = fopen('newfile.txt', 'wt');
tline = fgetl(fidi);
while ischar(tline)
  if ~isempty(tline) && tline(1) >= '0' && tline(1) <= '9'
    %line to keep
    fprintf(fido, '%s\n', tline);
  end
  tline = fgetl(fidi);
end
fclose(fidi);
fclose(fido);

edit: forgot to read the next line!
