save ascii from edit uicontrol

1). I have m file with 16 edit text using uicontrol like this :

 edit16=uicontrol('parent',win1,...
    'units','points',...
    'position',[320 60 30 15],...
    'backgroundcolor',[1 1 1],...
    'style','Edit',...
    'string','0',...
    'fontname','arial',...
    'fontsize',10);

 Save=uicontrol('parent',win1,...
    'units','points',...
    'position',[30 20 80 15],...
    'style','pushbutton',...
    'callback','save',...
    'string','Save',...
    'fontname','arial',...
    'fontsize',10);

and try tosave ascii using this save.m

a=get(edit1,'String');
b=get(edit2,'String');
c=get(edit3,'String');
d=get(edit4,'String');
e=get(edit5,'String');
f=get(edit6,'String');
g=get(edit7,'String');
h=get(edit8,'String');
i=get(edit9,'String');
j=get(edit10,'String');
k=get(edit11,'String');
l=get(edit12,'String');
m=get(edit13,'String');
n=get(edit14,'String');
o=get(edit15,'String');
p=get(edit16,'String');

save red.txt a b c d e f g h i j k l m n o p -ascii

and i cant save it,the error :

Attempt to execute SCRIPT save as a function:
D:\gui\save.m

Error in save (line 37)
save('a', 'b', 'c',
'd','e','f','g','h','i','j','k','l','m','n','o','p', '-ASCII');

Error while evaluating uicontrol Callback

2). And i wonder how to save this ASCII file in any folder,what is the command?

You need to name your save.m something else, something that is not the name of any MATLAB routine that is called upon by the code. You know that the "save" command inside your save.m is intended to refer to the built-in save command, but MATLAB says "Oh, you overrode save.m with your own code, okay, guess I need to call that code, even if it is the same file I'm already executing..."

You can specify a different location to save to:

save('C:\Documents and Settings\Thundercats\red.txt', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', '-ascii')

Thanks walter. I try myself it works using this :

savefile = 'br.txt'
a=str2num(get(edit1,'String'));
b=str2num(get(edit2,'String'));
c=str2num(get(edit3,'String'));
d=str2num(get(edit4,'String'));
e=str2num(get(edit5,'String'));
f=str2num(get(edit6,'String'));
g=str2num(get(edit7,'String'));
h=str2num(get(edit8,'String'));
i=str2num(get(edit9,'String'));
j=str2num(get(edit10,'String'));
k=str2num(get(edit11,'String'));
l=str2num(get(edit12,'String'));
m=str2num(get(edit13,'String'));
n=str2num(get(edit14,'String'));
o=str2num(get(edit15,'String'));
p=str2num(get(edit16,'String'));

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

but the output :

   4.0000000e+00
   3.0000000e+00
   0.0000000e+00
   1.0000000e+04
   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

For my Input in edit text

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

It seems some of the output is not recorded like B2 and M12. anywrong with this script?

[Walter Roberson]

Quoting the documentation on save -ascii:

Use one of the text formats to save MATLAB numeric values to text files. In this case:

    Each variable must be a two-dimensional double array.

    The output includes only the real component of complex numbers.

    MATLAB writes data from each variable sequentially to the file. If you plan to use the load function to read the file, all variables must have the same number of columns. The load function creates a single variable from the file.

In other words, using -ascii is the wrong thing to use for string variables.

You should fopen() a file, fprintf() the values in the appropriate format, and fclose() the file.

[Muhammad Habibie]

So you suggest using fopen()/fprintf() and fclose() but how I convert to ascii if my data get from edit. I just need the output same as the input from the edit text.
