Hello,
would you please give me an example of use of dataset? I am used to structures now, but I think that dataset could be easier to handle for my purposes. Say that I would like to see how dataset works having to import a simple txt data like:
a b c
1 2 3
4 5 6
7 8 9
Thanks for your example. Chiara

In general a DBMS is much better than MATLAB at managing data (dataset arrays try to emulate the functionalities of a database). In the long run I would invest time to learn SQL to manage data and interface it with MATLAB whenever computational complexity arises.
In my experience I started using only MATLAB and ended up executing 80% of descriptive statistical analysis with SQL Server!
