batch process images on Linux Ubuntu

Hi, I'm a Matlab rookie and I successfully managed to run a code in Matlab for superpixels creation. Now I am trying to batch process the same code for multiple images (respectively left.jpg and right.jpg and I'm hitting a wall.

I am using Matlab in no java mode as follow: TERMINAL>

    matlab -nojvm -nodisplay

Then I am trying to type in this which gives me an error (input character is not valid)

> PairModel$Img1"_"$Img2.out << EOF

Img1 and Img2 should be the following images I want to batch process: left.jpg and right.jpg but how do I tell that to Matlab?

Then I would like to call in the first task that generated the superpixels using the following code:

Fdir ='/works/scratch/TestMultipleImage/$Task';
WlrName = [ '$Task' '_' '$Img1' '_' '$Img2'];
PairList = [];
PairList = [ PairList; {'$Img1','$Img2'}];

The '$Task' is that the one I used to generate the superpixels? If yes, do I write the name of that function instead of '$Task'?

Thanks for any help,

Than you.
