for the purpose of testing

Maybe asking the authors would be a start instead of asking here.

Ask the author of the paper. Sometimes they provide the code.

Don't be surprised, if the code does not run on your computer. I'm afraid, that this is the usual case. There might be dependencies to other toolboxes, which cannot be offered for free, or the input data are not matching precisely enough. I've seen it too often, that it was impossible to reproduce the results.
