If a statement, or a row vector is too long to fit in one line, it can be continued to the next line by
typing three or more periods, then pressing <enter> to start a new line, and continue to enter
data. This is illustrated below for the data of w and z. Also, as mentioned before, we use the semi-
colon (;) to suppress the display of numbers which we do not care to see on the screen.
The data are entered as follows:

w=[300 400 500 600 700 800 900 1000 1100 1200 1300 1400.... % Use 4 periods to continue
1500 1600 1700 1800 1900 2000 2100 2200 2300 2400 2500....
