I'm tring to extract the dates from historical stock price data for Amazon.
My understanding is
a = importdata('AMZN.csv');
date = a.data(end:-1:1,1)
should do the trick, however, it extracts column 2 instead.
This is also true if I insert extra columns at the start of the csv file. I added a copy of the last column into the first column, and running the same code as above now extracts column 3 - the same column as in my first attempt.
What am I doing wrong?

try readtable instead
But, if you're set on (or stuck with) importdata, try looking at a and a.data directly and see if you can figure out what's going wrong
