My data file consists of 3 columns and 100,000 rows. I want my code to go down a series of rows and test each row for the following.
if column1 > 13 & column1 < 15 put all those rows in a matrix (including columns 2 & 3) elseif column1 > 2 & column1 < 4 put all these rows in a different matrix (including columns 2 & 3) end
What's a good approach to this?
