HELP please

[edhilyn]

im trying to do a matrix multiplication and adding here.. yet i cant.. because this error occurs : "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
at one.main(one.java:104) "

HELP ME please?

here's my code:

Wrap up your code with code tags, [code] ...code... [/code] This displays line numbers and syntax highlighting. I don't really want to count down to line 104 when it could be easily displayed for me..
