Hi,

I think I got it. It means class of ##N_1## persons having ##m## features, class of ##N_2## persons having ##m## features and so on.
Let me know if its correct.
Zulfi.

You gave very little context but based on what you have said, I think your interpretation is correct. There are ##N_1## m-dimensional samples, ##N_2## m-dimensional samples, etc. You've left out any context that would allow us to connect these numbers to "persons" or "features", so I have to assume you're right about those definitions.
