I am running MATLAB from command line using the following command on a linux system

$ matlab -nojvm -nodisplay < main.m

The command line ouput contains unexpected prompt characters (">>") at the beginning of the ouptut. The expected output, which is obtianed when running the code in the MATLAB command window is

>> main
Dimension 1: Range = [-9.93,9.93]
Dimension 2: Range = [-9.93,9.93]
Dimension 3: Range = [-9.93,9.93]
Size of a: 15180
Size of b: 32509

However, when run from the command line, the output looks like

$ matlab -nodisplay -nojvm < Collocate.m 
                            < M A T L A B (R) >

And keeps going on for a few more lines. I can't understand where the prompt symbols ">>" come from. Is there any way of getting rid of these?

Rather than piping the contents of the file to MATLAB, do you see this same behavior if you use the -batch startup option listed on this documentation page? I think that is more in-model for the operation you're trying to perform.
