error using horzcat for multiple files

hello everyone, i wrote this code to read text files with extension YO7, each file represents a month in the year, when i run it for 2 cards (2 months) it works, but when i add the third card or month it gives error, any ideas what to do here please?

for K = 1 : length(directory)
    filename = directory(K).name;
    fileID = fopen(filename,'r');
    formatSpec = '%s';
    A_cell = textscan(fileID,formatSpec);
    A=char(A_cell{1,1}{:,:});
    A(find(isnan(A)))=0;

      [rows,columns]=size(A);
      if columns~=105
          ArrayTemp=zeros(rows,105);
          ArrayTemp(1:rows,1:columns)=A;
          A=ArrayTemp;
          A=char(A);
          A(isspace(A)) = '0';
      end

      x1=filename;
      xtr=strcat('C:\Users\maa285\Desktop\New folder (2)',x1);
      fid = fopen( xtr, 'wt' );

      StationID = A(:,4:9);
      Year_of_Data = A(:,12:13);
      Month_of_Data = A(:,14:15);
      Vehicle_Class = A(:,20:21);
      Total_Weight_of_vehicle = A(:,25:28);
      Number_of_axles = A(:,29:30);
      A_Axle_Weight = A(:,31:33);
      A_B_Axle_spacing = A(:,34:36);
      B_Axle_Weight = A(:,37:39);
      B_C_Axle_spacing = A(:,40:42);
      C_Axle_Weight = A(:,43:45);
      C_D_Axle_spacing = A(:,46:48);
      D_Axle_Weight = A(:,49:51);
      D_E_Axle_spacing = A(:,52:54);
      E_Axle_Weight = A(:,55:57);

      %This is to convert the string to numbers so it can show the output:
      fprintf(fid, '%s %s %s %s %s',StationID, Year_of_Data, Month_of_Data, Vehicle_Class, Total_Weight_of_vehicle, Number_of_axles, A_Axle_Weight, A_B_Axle_spacing, B_Axle_Weight, B_C_Axle_spacing, C_Axle_Weight, C_D_Axle_spacing, D_Axle_Weight, D_E_Axle_spacing, E_Axle_Weight);

      Ans_3{K}=str2num(StationID);
      Ans_6{K}=str2num(Year_of_Data);
      Ans_7{K}=str2num(Month_of_Data);
      Ans_10{K}=str2num(Vehicle_Class);
      Ans_12{K}=str2num(Total_Weight_of_vehicle);
      Ans_13{K}=str2num(Number_of_axles);
      Ans_14{K}=str2num(A_Axle_Weight);
      Ans_15{K}=str2num(A_B_Axle_spacing);
      Ans_16{K}=str2num(B_Axle_Weight);
      Ans_17{K}=str2num(B_C_Axle_spacing);
      Ans_18{K}=str2num(C_Axle_Weight);
      Ans_19{K}=str2num(C_D_Axle_spacing);
      Ans_20{K}=str2num(D_Axle_Weight);
      Ans_21{K}=str2num(D_E_Axle_spacing);
      Ans_22{K}=str2num(E_Axle_Weight);

      %%to return the separated vectors into one new matrix with usable data:
        all{K} =[Ans_3{K},Ans_6{K},Ans_7{K},Ans_10{K},Ans_12{K},Ans_13{K},Ans_14{K},Ans_15{K},Ans_16{K},Ans_17{K},Ans_18{K},Ans_19{K},Ans_20{K},Ans_21{K},Ans_22{K}];
    end

Which line is the error occurring on?

Note: your code line

        fprintf(fid, '%s %s %s %s %s',StationID, Year_of_Data, Month_of_Data, Vehicle_Class, Total_Weight_of_vehicle, Number_of_axles, A_Axle_Weight, A_B_Axle_spacing, B_Axle_Weight, B_C_Axle_spacing, C_Axle_Weight, C_D_Axle_spacing, D_Axle_Weight, D_E_Axle_spacing, E_Axle_Weight);

is suspicious. Each of those variables looks to be a character array with multiple rows. fprintf() in MATLAB "uses up" all of the first column of the first variable, then all of the second column of the first variable, and so on, before it starts using the second variable at all, so you would get garbled output unless I have missed some reason why A really only has one row even though you consistently refer to it as if it has multiple rows.

A has multiple rows maybe more than 200000, if you notice in the code i extracted data from a as column vectors and called them Ans_ and then converted the answers into numeric vectors, then i gathered them in a matrix called all, for example the first column in all is Ans_3{K} and it has 200000 rows

[Walter Roberson]

If A has multiple rows then that fprintf() is definitely wrong. You need

temp = [cellstr(StationID), cellstr(Year_of_Data), cellstr(Month_of_Data), cellstr(Vehicle_Class), cellstr(Total_Weight_of_vehicle), cellstr(Number_of_axles), cellstr(A_Axle_Weight), cellstr(A_B_Axle_spacing), cellstr(B_Axle_Weight), cellstr(B_C_Axle_spacing), cellstr(C_Axle_Weight), cellstr(C_D_Axle_spacing), celstr(D_Axle_Weight), cellstr(D_E_Axle_spacing), cellstr(E_Axle_Weight)] .';
printf(fid, '%s %s %s %s %s\n', temp{:});

[Walter Roberson]

I suggest you command

 dbstop if error

and run the program, and when it stops, examine the size of each of those Ans_ cell arrays.

mr walter i did it, i found out that the error is in ans_7, is not consistent with the rest of the columns. thank you

i will try the line you suggested

[MAHMOUD ALZIOUD]

still gives: Error using horzcat Dimensions of matrices being concatenated are not consistent.
