How can I increase the text size of the MATLAB 2012b help documentation?

May I know how to increase the font size in the help documentation in MATLAB 2012b?

Answer 1

[Honglei Chen]

You can use Ctrl + to increase the font size.

TQ for your reply. Ctrl + is by using keyboard. How can I use the mouse to increase the font size?

[Honglei Chen]

I don't know how to do it with mouse in R2012b.

Ctrl+ only changes the font size for the current session. Here is a way to change it permanently:

Within your Matlab configuration folder (./matlab/Rxxxx/ under Unix), go to HtmlPanel/.JxBrowser/xulrunner-version--unknown-profile. Here, create a file user.js which contains the line

    user_pref("layout.css.dpi", 192);

After that, restart Matlab.

This tells the help browser which is actually a xulrunner application (i.e. based on Mozilla's webbrower technology) to assume a higher monitor resolution and scale the display accordingly. It appears that the standard value is 96, and that changes take only effect in multiples of this number, i.e. 96-191 doesn't change anything, 192-287 leads to a factor two, beyond that three, etc.

I tested this with Matlab R2013a, but I suspect that the same holds for some earlier versions of Matlab.
