How to run m-file from another m-file by input string
显示 更早的评论
I have tried this code below trying to immediately run an m-file that was just created in another m-file :
savename = input('name : ');
f=fopen(savename,'w');
%%%writes in the created m-file
fclose(f);
run(save_name);
The above code neither produce any error or runs the script. Any comments? thanks.

I was able to do something similar but had to change your code slightly
% use 's' to indicate that the result is a string and not an
% expression that should not be evaluated
savename = input('name : ', 's');
% open the file
f=fopen(savename,'w');
% write a line to print out a statement
fprintf(f,'fprintf(''this is a test\\n'');');
% close the file
fclose(f);
% use savename rather than save_name
run(save name);
And this worked fine with the output being
this is a test
and the input being test.m.
What are you writing to your m file? If you run this script from the Command Window, does it work or does it only fail when you try to call it from the other m file (as above)?

try this:
...
fclose(f);
rehash;
run(save_name);
also make sure that your variable save_name does not include the extension .m, while the file that you create does include it. So that would be something like:
savename = 'test';
f = fopen([savename '.m'],'wt');
...
fclose(f);
rehash;
run(savename);

Interesting (and thanks for pointing this out)... Entering a script name with the extension .m (and without a filepath) produces an error on an old version of Matlab (R2008b), but it seems to work just fine on a more recent version (R2013a)...

I do that some times just by doing this:
another_script = input('script name: ','s'); % and type the name of your other script
run(another_script);
with no need of either fopen or fclose

Arief's code is creating a script from within another, and so needs the fopen and fclose.
