Generated "*.m" file could not be real time updated

hello:

As showed in figure. I have a 'main.m' file, which feature is read external files and generate 'a.m' file, then run 'a.m'. I found that, after run('a.m') on 'Step 2', the resault represent that ‘a.m’ is not newest. After run 'main.m', when I check 'a.m', it is newest.

My question is there any way to run newest 'a.m' in 'main.m'.

Thank you.

For performance MATLAB caches executed functions and scripts. To clear that script from the cache call CLEAR:

filename = 'a.m';
clear(filename)
run(filename)
