Hi there,

First of all, thanks so much to everyone who has been helping me with my code so far; you have been so helpful!

Okay, now that i have my code working nicely i want to run it several times in a row with various input parameters.  My function analyzes data and outputs a struct based on the input parameters and I want to have it provide output for several different inputs.

In the command console it would look like this:

>> interval_1min = myFunction(1)
>> interval_2min = myFunction(2)
>> interval_3min = myFunction(3)
..
..
..

and I want to do this for a bunch of different inputs but each time it takes about 2hrs so I want it to do a bunch of them overnight.  I hope this is clear.  I'm pretty sure it is simple to do this with an m-file or something but I am a MATLAB beginner so I dont know the best way to go about it.

Thanks in advance!!

Don't do this!!

Thats not what i want though.  I want the output from each iteration of my function to be assigned to a variable.  I want to have the code get executed overnight just as if I was sitting beside the computer and typing in the next command when the previous one finished.  Understand?

How about a while or for loop that just loops the number of functions or whatever you want to do?  Each loop, you could be reading an input with your function parameters.  Make sure that for ever output, you save it (use save for variables or saveas for figures) and close it, or else MATLAB will get bogged down quickly.

I understand, but what I'm saying is that you should NOT assign the
output to variables defined like that.  And I gave you that reference
in the FAQ because it not only shows how to assign variables
correctly, but also shows a for loop, which is what you're looking
for.
Did you not grasp that when you read the FAQ?

No sorry I did not.  Maybe if you would have offered a little more explaination to your solution than "dont do this" i would have grasped it.

To be even more explicit, do something like this:

% pre-allocation goes here.
for ii = 1:5
    interval(ii).min = min(rand(ii));  % For example
end
% Now look at:   interval(4).min


OR this:


% pre-allocation goes here.
for ii = 1:5
    interval_min{ii} = min(rand(ii));  % For example
end
% Now look at:   interval_min{4}

In your opinion, how long of a tutorial should we write in response to 
each of the several hundred questions posted each day?

Just a passing thought: If your code works in serial fashion, why don't you consider PARFORing it?

You should try to digest the FAQ, the answer you received was the correct one. It is hard to manipulate variables if you create them in the way you describe. You will end up having to use the eval function, which is really not ideal. If you index as suggested then your code will be more elegant, compact and easy to understand. It will also make it easier to extract the data which you want.
