i have this code

i ahve this code and i donțt understand why is not working .

clear all

clc

close all

fid = fopen('corpusjuridicspatii.txt');

x=fread(fid,'*char');

binary = dec2bin(x,8);

binary_t=transpose(binary);

bin=binary_t(:)-'0';

i =1;

j =1;

while (i<length(binary_t))

cuvinte{j} = '';

while binary_t(i)~=32 % cat timp nu am dat de caracterul spatiu, concatenam caracterele la celula care contine cuvantul respectiv

cuvinte{j} = [cuvinte{j},char(binary_t(i))];

i = i+1;

end

j = j+1;

i = i+1; % cand dam de spatiu, sarim peste el ca sa nu ne blocam

end

[cuvinte_unice, ida, idb] = unique( cuvinte ) ;

counts = accumarray( idb, ones(size(idb)) ) ;

% cuvintele unice si numarul lor de ocurente

[ocurente_cuvinte_unice_sortate, indici_cuvinte_unice_sortate] = sort(counts,'descend');

frecvente_cuvinte_unice_sortate = ocurente_cuvinte_unice_sortate/length(cuvinte);

cuvinte_unice_sortate = cuvinte_unice(indici_cuvinte_unice_sortate);

for i = 1:length(cuvinte_unice_sortate)

['PROGRES DE ',num2str(i/length(cuvinte_unice_sortate)*100),' %']

cuvinte_numeric(find(strcmp(cuvinte,cuvinte_unice_sortate(i)))) = i;

% for j = 1:length(cuvinte_unice_sortate)

% if strcmp(cuvinte(i),cuvinte_unice_sortate(j))

% cuvinte_numeric(i) = j;

% break;

% end

% end

end

a=unique(cuvinte,'stable');

b=cellfun(@(x) sum(ismember(cuvinte,x)),a,'un',0);

Hi Armina,

The error in the code is occurring because the while loop is not properly checking if the index ‘i' exceeds the length of the ‘binary_t’ array. This can cause the loop to run beyond the length of the array and result in the error message you are seeing.

To fix this error, you should add a check to ensure that ‘i’ does not exceed the length of 'binary_t’ array. Here is an updated version of the code that should work:

clear all 
clc 
close all 

fid = fopen('etxt1.txt'); 
x=fread(fid,'*char'); 
binary = dec2bin(x,8); 
binary_t=transpose(binary); 
bin=binary_t(:)-'0'; 

i =1; 
j =1; 
cuvinte{j} = ''; 

while (i<length(binary_t)) 
    cuvinte{j} = ''; 
    while (i<length(binary_t) && binary_t(i)~=32) % cat timp nu am dat de caracterul spatiu, concatenam caracterele la celula care contine cuvantul respectiv 
        cuvinte{j} = [cuvinte{j},char(binary_t(i))]; 
        i = i+1; 
    end 

j = j+1; 
i = i+1; % cand dam de spatiu, sarim peste el ca sa nu ne blocam 
end 

Please note that I have also initialised the ‘cuvinte’ variable before entering the loop to remove the warning shown in the attached screenshot. This warning appears because the length of this variable is varying at every iteration of the loop.

Hope this helps!
