Hallo, I have an array containing six rows and 3 columns. My task is to calculate the arithmetic average of the elements in the columns and add it as a seventh row to the array. How can I do that? I added a txt-file with the array. --3923272.1087216678518.JavaMail.quiq.tekken Content-Type: text/plain; name=test1.txt Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=test1.txt Content-Description: array 2,000 9,000 16,000 3,000 10,000 17,000 4,000 11,000 18,000 5,000 12,000 19,000 6,000 13,000 20,000 7,000 14,000 21,000 --3923272.1087216678518.JavaMail.quiq.tekken--
