You have been provided stock data for Boeing in 2018 (from January 1st to December 31st). The data includes the opening (column 4) and closing values (column 7) for the day, along with the highest (column 5) and lowest value (column 6) for the day. I need to be able to remove the rows where opening = 0 without hardcoding.
Code:
Opening = BoeingStock(:,4);
if Opening == 0
BoeingStock(:) = []
else
BoeingStock(:,:0 = [:,:]
end
