While you can use pctRunOnAll with batch, it's a little awkward. Here's what you need to do:
j = batch(@pctRunOnAll, 0, {'script1'}, 'Pool', 10, 'CaptureDiary', true)
Here we're using the form of batch which takes a function handle - in this case @pctRunOnAll. Then, we must specify the number of output arguments from that function - which is 0, and then the input arguments as a cell array, {'script1'}.
One other option you might wish to explore is wrapping up your task inside a function, and then you can use parfeval to run multiple iterations. This is also compatible with batch.
