I can't find the gaussian noise generator in the simulink ?

i have matlab R2016b, i have installed all the toolboxes(including the communication toolbox, and the DSP) except 9 of the toolboxes(e.g. financial) . i can't find the gaussian noise generator (nor the Noise Generators sublibrary)

You have mentioned that you cannot locate the Gaussian Noise Generator that should be in the Communications System Toolbox according to documentation online:

https://www.mathworks.com/help/comm/ref/gaussiannoisegenerator.html

As mentioned in the documentation for that block, it will be removed in a future release.

If you have a model that contains a Gaussian Noise Generator block, you can always find its parent library by right-clicking the block and selecting > Locked Library Link > Go to Library Block (CTRL+L) or by executing the following command:

There are also a few other Simulink blocks that may be easier to find:

1. MATLAB Function and randn

This is the suggested replacement for Gaussian Noise Generator mentioned in the release notes for R2015b, which can be viewed here:

Go to R2015b > Functionality being changed or removed

2. AWGN Channel block in the Communications System Toolbox

With this block, you can add white Gaussian noise to a real or complex input signal. Refer to the following link for more information on this block:

Thank you for you answer! It's trouble with me for a long time, I decide to uninstall matlab2015.
