i want to have a 2d list of floats to be accessible and changeable from multiple mxj objects. i guess i need some kind of global variable for this.

i tried making a specific mxj object for the global variable with a public static Float[][] but i can't write the list nor read from other mxj objects.

if i am declaring, accessing or changing the global variable in a wrong way, could somebody point out the right commands for doing this?

or are there maybe other solutions for my problem?
