How do I input/use functions from stats?

For example: if I input "stats::variance(2, 3, 5)" I get the following error Error: Unexpected MATLAB operator. % with an arrow to the operator "::"

It's an example from the matlab documentation: https://de.mathworks.com/help/symbolic/mupad_ref/stats-variance.html Example 1

If I leave "stats::" I get the message "Undefined function or variable 'variance'."

Thanks everyone who tries to help me :)

Any command that includes "::" in the name is a MuPAD function intended for use in a MuPAD Notebook. Those functions cannot be used in a MATLAB function or in the MATLAB Command Window without using the evalin method or the feval method of the symengine object to call them.

"::" is no Matlab operator, so I cannot guess your intention to use it.

In fact, Matlab does not have a command called "variance". You can find the command for calculateing variances in the documentation:

docsearch variance

The var command does not accept (2,3,5) as input. Perhaps you want:

var([2,3,5])

Did you work with Matlab before? If not, reading the "Getting Started" chapters of the documentation is recommended and Matlab's Onramp helps to learn the basics also.

Thank you very much. It's a copy from an example in the matlab documentation: https://de.mathworks.com/help/symbolic/mupad_ref/stats-variance.html Example 1

Ah, this explains the non-Matlab syntax. Sorry, I do not have the MuPad toolbox.
