Hello, I would like to access only to certain lines (rows) in my datastore and save them to a matrix. What I am doing now is:
1. Read all the datastore and save the data in a matrix.
2. Eliminate the data I don't want (by removing rows from the matrix).
It works, but I'm wasting a lot of time storing useless data in the first step. Is it a way to directly save the data that I want?
Information: my datastore is a collection of files, all of them with the same structure: two columns filled with numeric data. Each file has 100 rows, but I only want to save the first 60.
