I have a set of values which i have saved in MAT file and along with several m-files compiled and created a stand alone application. In the stand alone application, I have opened the MAT file data and edited some values and saved data again into same MAT file to override the data. But instead of overriding the MAT file it is creating a new MAT file in the same directory of exe file (outside world), but what i want is to override the same MAT file which i have used during compilation.
x = load('Values.mat');
x1 = x.x1;
x2 = x.x2;
save 'Values.mat' x1 x2;
used to override the data
What i need to do, in order to override the data into the same MAT file which loaded during compilation..?

I have used the following code -
save 'Values.mat' 'x1' 'x2' '-append';
which working perfectly fine....

The init callback is part of MATLAB execution and does not get included during code generation. You may be able to achieve what you are trying by using the Rapid SIMulation target (rsim.tlc). See:

I didn't know why rtw document applies my program about compiled standalone application...but i have read the document and change the attributes of my MAT file into write mode before saving it again so as to override the data. But still i am facing the same problem.
