Display value of a variable within ' '

Hi,

I am trying to call Stata within Matlab with the following command. run_id is the argument I am passing to stata as an index.

My question is: this run_id can take different values like 1,2,3,.... how to display the value of the run_id within ' ' such that the do-file take these values as argument. I checked but couldn't find a corresponding answer. Thanks, in advance!

system([stata_location ' -b do mydir/mydofile run_id']);

system([stata_location ' -b do mydir/mydofile ' num2str(run_id)]);

No, actually this doesn't solve the problem. because it is changing the name of the do file to mydofilerun_id.do.

Instead, I followed this https://www.mathworks.com/matlabcentral/answers/386805-how-to-pass-variable-argument-using-system-command and it solved the problem, seemingly.

Thanks, though.
