How to run multiple programs

Hi,

Anybody know a code to run (say) 3 programs one after another without having to give a command to run each program please?

What I want is something like the following

for i=1:3
    test(i).m;
end

Thanks

Just put in an .m file (script):

 test1; %you don't even need the .m here
 test2;
 test3;

And your three programs will run consecutively, provided they are in the path or the current folder.

thanks. If I have more than 3 programs is there a for loop I can use to do it easily. I dont know how to write a loop to change 1,2,3 in test1, test2, test3.

[José-Luis]

Then you can use something like what Geoff proposed:

 your_string = 'test';

 for ii = 1:3
    current_prog = [your_string num2str(ii)];
    run(current_prog)
 end

thanks to both of u!!

Could u pls explain this error I got .. "okkoma is the name I gave to the program.

Thanks

Undefined function or variable 'your_string'.

Error in okkoma (line 3)
    current_prog = [your_string num2str(ii)];

[José-Luis]

 current_prog = ['okkoma' num2str(ii)];

[dav]

I am sorry may be it wasn't clear I named the following code "okkoma"

your_string = 'test';

for ii = 1:2
    current_prog = [your_string num2str(ii)];
    run(current_prog)
 end

But the programs run by the code "okkoma" are named test1, test2...

Is that wrong?

When I did the proposed change I got

Error using run (line 55)
okkoma1 not found.

Error in okkoma (line 5)
    run(current_prog)

Thanks much

dav - so your main script is named okkoma.m and you want to run the two (or more) scripts named test1,test,etc.

Then, the code within the okkoma.m should be what José-Luis proposed earlier

 your_string = 'test';
 for ii = 1:2
    current_prog = [your_string num2str(ii)];
    run(current_prog)
 end

which will call run on the scripts test1, test2, etc.

Dav - it seems that you could use the run command to do this. If test is a cell array of strings with each string corresponding to a "program" (script or function with no arguments), then try

 test = {'whos','what'};

 for k=1:length(test)
     run(char(test{k}));
 end

If you run the above, the first command (whos) will list all variables in the workspace, and the second command (what) will list the MATLAB files in the folder.

hello,

Thanks for the response. But test1, test2, and test3 are complete matlab codes i am using. I dont understand why you use length(test) in your code.

Test1, test2, test3 are 3 different matlab codes

[Geoff Hayes]

dav - it wasn't clear from your question what the names of are your scripts were. So in the above example, I created an array of strings where each string corresponded to a script. In this case, I used the built-in MATLAB functions whos and what. length is used to determine how many programs/scripts should be run (since the length(test) is two), and then we call run on each element of test. This could easily have been set to

 test = {'test1', 'test2', 'test3'};

Thanks a lot.
