Experiment by using a Matlab's demo data set and publish to journal/conference I hope my question is within the topic of this forum.

I would like to test an algorithm to a real application data and publish in a journal/conference. However, I cannot acquired my own data set myself and I am thinking to use one of Matlab's demos data set that is mentioned from a real experiment.

Is it acceptable to use those data set for a conference/journal publication?

Thank you
As an alternate suggestion, you might try calling people who either do similar research, or are involved in the application the research covers, and get a copy of their data. I've never done it at a publishing level, and I don't know what kind of field you're in, but I have had success with this for some minor projects I've done.

Generally, it's not in the exact format you want, but real data is better than suspicious data. And reformatting is a lot easier than collecting tons of data.
