Download and decompress (stock prices: date, open, high, low, close, volume) (18MB)  stckPrcs.tar.bz2. in Octave, ‘load’ BDXA (in B/BDXA.us.txt and Octave needs to be in the directory where BDXA.us.txt is): BDXA=load(‘BDXA.us.txt’); at which data the BDXA had the highest price (need to use functions below for date as solution): m = max(BDXA(:,2)), i = find(BDXA(:,2) == m), date = BDXA(i, 1) For the submission send in the plain text the commands you used in part 1) (a,b,c) : there should be 3 lines. send in the plain text the ‘date’ variable you found in part 2) b): there should be one number.
