I stumble across some MATLAB codes about data file paths, something like:
data=csvread(sprintf('../data/cdflevel%dtable.csv',cdflevels(i)));
I am not sure what '../' does. Anyone can explain it?
../ moves one folder up from the current directory, before then changing to the data directory in the parent folder. It's not specific to MATLAB, just a standard way of navigating a file system.
