about statistics toolbox

Hello, every. I'm new to MatLab. Just a simple question: How could I know whether I have statistics toolbox? Should I buy it additionally? How should I launch it? Thank you very much.

The Statistics toolbox requires a separate license. You can check the installed toolboxes with:
>> ver
-------------------------------------------------------------------------------------
MATLAB Version 7.9.0.529 (R2009b)
MATLAB License Number: *
Operating System: Linux 2.6.25-gentoo-r7 #1 SMP Mon Sep 29 17:50:02 CEST 2008 x86_64
Java VM Version: Java 1.6.0_12-b04 with Sun Microsystems Inc. Java HotSpot(TM) 64-Bit Server VM mixed mode
-------------------------------------------------------------------------------------
MATLAB Version 7.9 (R2009b)
Image Processing Toolbox Version 6.4 (R2009b)
Statistics Toolbox Version 7.2 (R2009b)

However, having it installed does not mean that you are licensed to use it (this can be the case on a multi-user machine where some users are licensed for some toolboxes, and others are not).

Try to use a statistics command, like disttool:
>> disttool

So, I am not licensed for the statistics toolbox.

This is confusing, since it is listed. You may try:
>> ver('statistics')

If it gives a warning, you are not licensed.

Sheng-Yun, if you have a recent copy of the MATLAB Student Version, then you do have Statistics Toolbox. You don't need to launch it, you just use the functions in it like anything else in MATLAB. If you have it, the help browser will include a tab for Statistics Toolbox.

If you're using something other than the Student Version, Sebastiaan's advice is what you want to follow.

Hope this helps.

Enter 'ver' (without the quote marks) at the command line and you will
see which toolboxes are installed.
