How to create an mfile in my app in the working directory?

Hi All

I have a code in my app and want it also to create an mfile with some lines in a folder I want and then run it. How is this possible ?

and how do I write a line that it can save an already open figure ?

I tried :

            txt=str(saveas(f,'test','jpg'));
            edit file.m
            FID=fopen('file.m',w);
            fprintf(FID, '%s', txt);
            fclose(FID);
            
            run('file')

txt=str(saveas(f,'test','jpg'));

saveas doesn't return anything so not sure what do you want to do by this?

That code looks like nonsense. What are you trying to do with the saveas() function?

I tried to save an open figure via matlab but this did not work after compiling. I resolved it . It was actually working inside the app
