Hello,
I want on "y" axis linear amplitude instead of decibel amplitude. It's a signal analyzer toolbox.
I tried add a custom function "db2mag" in a preprocessing label, but MatLab sent me warning: To many inputs arguments.
Anyone know How to change db to linear magnitude in signal processing toolbox?

That does not appear to be an option. The best you can likely do is to export the spectrum and then plot it yourself.

Yes, its an alternative but I have a lot of data and it is very easy to analize signal in that signal processing toolbox. When I plot it I can't use many options like vertical markers, display peaks etc.

The Signal Analyser is designed in a way that it gives magnitude in decibel scale. If you wish to get the data in linear magnitude then you will have to export the data and plot it outside Signal Analyser. For more details on Signal Analyser capabilities I suggest you go through its documentation.
