The Semicolon Symbol

8 十月, 2015 - 17:29

The semicolon symbol at the end of a line suppresses the screen output. This is useful when you want to keep your command window clean.

Type the following entry and press the Return key:

» y=2+2

The following output is displayed:

y=

4

Now, press the up arrow key to recall our initial entry

» y=2+2

And insert a semicolon as follows:

» y=2+2;

No numerical result is displayed however MATLAB stores the value of y in the memory. We can recall the value y by simply typing y and pressing Return.
