hi all, i write a code to call text file in edit text(matlab GUI).but not call as same format, if any changes in edit text and save in other text file, it does not save as same format. so, what i change in code to save and call as same format after applying the push bottom.
fid = fopen('IO_PROCESS.txt','r');
if fid~=-1 %if the file doesn't exist ignore the reading code
set(handles.edit1,'String',fscanf(fid,'%s'))

The question is not clear. What kind of "format" do you mean? Can you post a relevant example?

the text file as given below,
fgdfgdfgjatsggdg
gddffghh
heat_1 = 40
heat_2 = 500
heat_3 = 200
heat_4 = 5
gas_ = 40.58
gas_CO2 = 0.000
gas_H2 = 7.71
gas_H2O = 0.000
gas_N2 = 51.71
the problem is to call this text file as same format in edit text box in matlab GUI. 2nd thing is that if i change same value in the given edit text and save in other text file, it have same format as previous with changeable data.

I not sure, what the problem is. It would be helpful if you mention, which problem you observe.
Maybe fscanf(fid, '%s') imports the first lien only? Then:
Str = fileread('IO_PROCESS.txt');
CStr = splitstr(Str, '\n');
set(handles.edit1, 'String', CStr);
...
CStr = get(handles.edit1, 'String');
fid = fopen(FileName, 'w');
if fid == -1
error('Cannot open file: %s', FileName);
end
fprintf(fid, '%s\n', CStr{:});
fclose(fid);
