Create new data sheet from fprintf code outputs

I'm working on my code. My code is calculede after the some operation and finally output like this;

%%
                   
   if [value] ~= 0 
       if Diff<3 && Diff>-3
           
   fprintf('\n %4f En "%s" Name , Comment:"%s", Dif:%.2f , Int(%%):%.2f ,  FD:%4f.\n'  , En ,Name, comment , Dif, int, FD )      
       end
   end

outputs:

86 En "X1" Name , Comment:"Y", Dif:0.68 , Int(%):3.56 , FD:0.92258

181 En "X2" Name , Comment:"Y", Dif:1.17 , Int(%):57.00 , FD:0.873798

241 En "X3" Name , Comment:"Y", Dif:1.36 , Int(%):7.27 , FD:0.887565

258 En "X3" Name , Comment:"Y", Dif:0.15 , Int(%):18.41 , FD:0.989895

351 En "X3" Name , Comment:"Y", Dif:1.05 , Int(%):35.60 , FD:0.940446

352 En "X4" Name , Comment:"Y", Dif:1.05 , Int(%):35.60 , FD:0.940332

605 En "X3" Name , Comment:"Y", Dif:1.17 , Int(%):45.49 , FD:0.961645

605 En "X4" Name , Comment:"Y", Dif:1.17 , Int(%):45.49 , FD:0.961579

1392 En "X5" Name , Comment:"Y", Dif:2.28 , Int(%):99.85 , FD:0.965726

I tried get a matrix from fprintf outputs are inculude Name and FD values with that code like this

   %%
                   
   if [value] ~= 0 
       if Diff<3 && Diff>-3
           
   fprintf('\n %4f En "%s" Name , Comment:"%s", Dif:%.2f , Int(%%):%.2f ,  FD:%4f.\n'  , En ,Name, comment , Dif, int, FD )      
    fds=[Name,FD]   
       end
   end      
   

but it doesn't work. İ couldn't find another solution.

Some people might be thinking of suggesting that you assign the output of fprintf to something that you save. However the returned output of fprintf is the number of items converted, not the text. To get the text you would use sprintf() or compose()

Your loop is overwriting the variable every iteration. You should replace this:

fds=[Name,FD]

With this:

fds=[fds;Name,FD];

(don't forget to put fds=[]; at the start of your code)

A better idea is to create a suitably large array at the start of the code and index it in your loop.

I changed my code according your directions and its output only .X5 size En times

like

' X5

X5

X5

X5

X5'

but i need a matrix from outputs like;

X1 0.92258

X2 0.873798

X3 0.887565

X3 0.989895

X3 0.940446

X4 0.940332

X3 0.961645

X4 0.961579

X5 0.965726

first colomun is Name and second one is FD values.

Change the square brackets to round braces. That will give you a cell array instead, which allows mixing data types.
