Do you see the problem why the i doesn't increase after the loop from the for

heres the code where the i never increment :

 borne_actuel = borne1;
    borne_ideal = 0;
    distance_ideal = 0;
    distance_ideal_fin = distance;
    distance2 = 0;
    distance3 = 0;
    borne_invoulu = 0;
    borne_precedente = borne1;
    
    while 1
        
        for i = 1:150
            distance2 = matrixDistance(borne_actuel,i);
            distance3 = matrixDistance(i,borne2);
            if (distance2 <= autonomie && i ~= borne_invoulu)
                if (i == borne2)
                    borne_ideal = i;
                    break
                elseif (distance2 >= distance_ideal && distance3 < distance_ideal_fin)
                    distance_ideal = distance2;
                    distance_ideal_fin = distance3;
                    borne_ideal = i;
                                        
                end
            end 
        end        
        if (distance_ideal == 0.0)
            fprintf('Aucun chemin ideal\n');
            break
        end
        %ajouter la borne actuel dans un tableau pour suivre le chemin
        % tab.ajouter[borne_ideal];
        % test tab
        if (borne_ideal == borne_actuel)
            borne_invoulu = borne_ideal;
        end
        fprintf('%g\n', borne_ideal);
        borne_precedente = borne_actuel;
        borne_actuel = borne_ideal;
        if (borne_actuel == borne2)
            %on est arrivere
            fprintf('GoodJob\n');
            break
        end
        borne_ideal = borne1;
    end
end

I already see something the command window display condtanstly the number of the input I enter. So for exemple I enter 11. The command window reply. This is what it happen like even if no fprintf is in rhe foor loop

11 11 11 11 11 11 ... And I have to do ctrl-c to be able to end the function

I coulldn't really put the code because it has like 20 called function probably so it will be hard to understand.

borne is like but i coould give you more information.

The program is to a person who has an electric car and it will input initial charging station and final charging station.

the program calculate and tell wich charging station depending on the autonomy of the car (autonomie).

this is the code complete

function [unChemin,cheminPossible] = OptimiserChemin ()
    [tab,tf] = CreerTrajet ();% return [borne
    borne1 = tab(1);
    borne2 = tab(2);
    autonomie = tab(3);
    [matrix] = ChargerMatrice (1);
    matrixDistance = matrix;
    [matrix] = ChargerMatrice (2);
    matrixDuree = matrix;
    distance = matrixDistance(borne1,borne2);
    duree      = matrixDuree(borne1,borne2);
    fprintf('%g\n%g\n%g\n',distance,duree,autonomie);
    if (tf == 0)
        cheminPossible = 0;
    end
    
    if (distance < autonomie)
        %aller au point
    end
    
    borne_actuel = borne1;
    borne_ideal = 0;
    distance_ideal = 0;
    distance_ideal_fin = distance;
    distance2 = 0;
    distance3 = 0;
    borne_invoulu = 0;
    borne_precedente = borne1;
    
    while 1
        
        for i = 1:150
            distance2 = matrixDistance(borne_actuel,i);
            distance3 = matrixDistance(i,borne2);
            if (distance2 <= autonomie && i ~= borne_invoulu)
                if (i == borne2)
                    borne_ideal = i;
                    break
                elseif (distance2 >= distance_ideal && distance3 < distance_ideal_fin)
                    distance_ideal = distance2;
                    distance_ideal_fin = distance3;
                    borne_ideal = i;
                                        
                end
            end
        end
        if (distance_ideal == 0.0)
            fprintf('Aucun chemin ideal\n');
            break
        end
        %ajouter la borne actuel dans un tableau pour suivre le chemin
        % tab.ajouter[borne_ideal];
        % test tab
        if (borne_ideal == borne_actuel)
            borne_invoulu = borne_ideal;
        end
        fprintf('%g\n', borne_ideal);
        borne_precedente = borne_actuel;
        borne_actuel = borne_ideal;
        if (borne_actuel == borne2)
            %on est arrivere
            fprintf('GoodJob\n');
            break
        end
        borne_ideal = borne1;
    end
end

the code of ChargerMatrice:

this code return a matrix of the distance between (bornes1,borne2)

function [matrix] = ChargerMatrice (choixOption)
   
        if (choixOption == 1)
          file = fopen('MatriceDistances.txt', 'rt');
                 
    %On s'assure que le fichier est disponible.
          if file ~= -1
            maintable1 = readmatrix('MatriceDistances.txt');
            maintable1(1,:) = [];
            maintable1(:,1) = [];
            matrix = maintable1;
            fclose(file);
          else
              fprintf('Une erreur est arrivée avec l''ouverture du fichier MatriceDistances.txt');
          end
        elseif (choixOption == 2)
            file = fopen('MatriceDurees.txt', 'rt');
                 
    %On s'assure que le fichier est disponible.
          if file ~= -1
            maintable2 = readmatrix('MatriceDurees.txt');
            maintable2(:,1) = [];
            matrix = maintable2;
            fclose(file);
          else
              fprintf('Une erreur est arrivée avec l''ouverture du fichier MatriceDurees.txt');
          end
        else
            fprintf('Erreur! Veuillez choisir un nombre entre 1 et 2 correspondant à la matrice à afficher');
        end
end
