how to take just 10% of my whole data and then train it?

Hi

i have a 500*10 matrix of data and now i want to use just first 10% of rows. how can i do this?

[Adam Danz]

10% of all elements in the matrix?

10% of the columns or rows?

I also recomment using cvpartition as Cris LaPierre recommended. If you do not have the Stats & ML toolbox, use randperm to select indices of the matrix.
