Hi, I am working on an Infography about running big data with matlab. I need the general commands used to create the datastore and then the tall array. For example, for .csv files.
Thank you very much.

The general procedure is that you create the datastore and then convert it into a tall array. If the data is relatively straightforward then the call to datastore is simplified. But if the data has missing data, several different types, header lines, etc... then you can call additional options with datastore (see the doc).
In the simplest case it can be as easy as:
ds = datastore('path/to/my/data.csv');
T = tall(ds)
