Trouble in Matlab writing the symbol ^

[lognok]

Hi there,
My Matlab (2006a) has problem with my danish keyboard-layout, as it refuses to write the (hat/power)-sign ^
When I enter the ^ key, it doesn't show (also tried to press space as this seams to bring it forth in gedit or any other command environment), instead it super scripts the next number I enter. So if I enter 9^9, it shows 9⁹.

If I change my keyboard-layout to Denmark+eliminate dead keys it works, but then I can't write brünger, it becomes br"unger.

Funny thing is when I write some code in gedit which includes the ^ sign and paste it into Matlab (either editor or command line) then it displays correctly and runs!!??.

Is there a way for me to fix this?

Thanks for any reply.

Hi! What happens if you try typing ^ and then a space after? It should work... If not, I know there are ways to configure keys separately, i'll take a look for you.

Typing the space should work. Otherwise you can also run matlab as "matlab -nojvm" (it now runs from the terminal console), but it is uglier..

Pressing space doesn't do anything.

If I type: 9 ^ 9 it gives: 9⁹
If I type: 9 ^ [space] it gives only 9, so pressing space right after the ^ sign doesn't produce anything.

But thanks for your suggestions.

I have the same problem on a Norwegian keyboard layout.
I just use ViM for editing my m-files to work around it. There are lots of Matlab-related
scripts out there, and the editing functionality of ViM far surpasses Matlab's editor.

There is a bug in Matlabs Java VM that prevents the use of any dead key + space bar combination...

In my finnish keyboard this means that ~ and ^ don't work.

You can fix the problem by remapping the characters to some other keys. I use the following script to map ^ to F11 and ~ to F12.



#!/bin/sh
xmodmap -e "keycode 95 = 94"
xmodmap -e "keycode 96 = 126"


You have to run the script every time after restart (manually or automatically)

Thanks ahmatti, I'll use your script until the jvm problem is solved.

Cheers ahmatti,

In case anyone is wondering where to put that script I created a user-specific config file i.e. ~/.xmodmap with the contents posted by ahmatti.
