format data for floating to integer to ascii

i have data input in edit text like this :

   B2
     4
     3
     0
     10000
     M12
     3
     1
     1
     1000
     0
     240
     120
     1520
     0

but when i use save ascii like this command :

    save(red.txt,'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','-ASCII'),

the variable from input using

b=str2num(get(edit2,'String'));

and edit text at least 16

edit1=uicontrol('parent',win1,...
    'units','points',...
    'position',[130 200 30 15],...
    'backgroundcolor',[1 1 1],...
    'style','Edit',...
    'string','',...
    'fontname','arial',...
    'fontsize',10);;

i get this :

   6.6000000e+01   5.0000000e+01
   4.0000000e+00
   3.0000000e+00
   0.0000000e+00
   1.0000000e+03
   7.7000000e+01   4.9000000e+01   5.0000000e+01
   3.0000000e+00
   1.0000000e+00
   1.0000000e+00
   1.0000000e+03
   0.0000000e+00
   2.4000000e+02
   1.2000000e+02
   1.5200000e+03
   0.0000000e+00
   0.0000000e+00

how do you make the same as the input?

This is the same question you asked before and I answered in http://uk.mathworks.com/matlabcentral/answers/251588-save-ascii-from-edit-uicontrol#comment_319269

Values you get from the String property of a uicontrol() are always strings until you convert them to numeric. Just write them out as strings.

b = get(edit2,'String');
fid = fopen('red.txt', 'wt');
fprintf(fid, '%s\n%s\n', a, b);
fprintf(fid, '%d\n%d\n%d\n', c, d, e);
fprintf(fid, '%s\n', f);
... and so on
fclose(fid);

Thanks a lot walter i have i try many times like fopen and fprint if i am using save ascii.but it seems i have to ask again to this forum. I wonder what is '%s\n%s\n and '%d\n%d\n%d\n' means? Because I am still learning matlab for beginner.

[Muhammad Habibie]

And if I wanted to add delimited tab next to B2 for additional description next to it.

and i try your script Mr Walter like this :

 fid = fopen(savefile, 'wt');
%fprintf(fid, '%s\n%s\n', a);
fprintf(fid, '%s\n', a);
fprintf(fid, '%d\n', b);
fprintf(fid, '%d\n%d\n%d\n', c, d, e);
fprintf(fid, '%s\n', f);
fprintf(fid, '%d\n%d\n%d\n', f, g, h);
fprintf(fid, '%d\n%d\n%d\n', i, j, k);
fprintf(fid, '%d\n%d\n%d\n%d\n%d\n', l,m,n,o,p);
fclose(fid);

but the output,it has another extra data :

77,49,50

B2
4
3
0
10000
M12
77
49
50
3
1
1
1000
0
240
120
1520
0
0

why?

[Walter Roberson]

You print out f twice once as string and then as integer.

From

help save
  ...
     '-ascii'                      8-digit ASCII format.
  ...
      For ASCII file formats, the save function has the following
      limitations:
      * Each variable must be a two-dimensional double or char array.
      * MATLAB translates characters to their corresponding internal
        ASCII codes.  For example, 'abc' appears in an ASCII file as:
            9.7000000e+001  9.8000000e+001  9.9000000e+001

To write the data otherwise you'll have to use formatted with fprintf as the other higher-level routines such as csvwrite can only handle numeric arrays and you've got character data here.

What, specifically, are you trying to accomplish; writing the data to a file or saving it for use internally to the application? If the latter you can forget about the format and just use save/load and retrieve what was written transparently.
