Why does my matlab function produce result more than I expect?

Please see the attached pdf file for the issue. Thanks!

use:

Testing;

Answer 2

Your function Testing has two outputs, and when you call the function the first output is displayed by default, unless you suffix the line with a semicolon. So instead of calling this:

Testing

you need to call this:

Testing;

Note that a function output is a totally different thing to the text that you are fprintf-ing in the command window: do not get confused between these.
