matlab error

You may have problem with Microsoft Java Virtual Machine. I have seen somewhere about this issue, but I forget the exactly solution.

Re: matlab error

The mathwork's solution don't work only with java virtual machine correctly installed, (SDK 1.3.1_08 and environment variable MATLAB_JAVA and value C:\jdk1.3.1_08\jre)
you should too select a text and copy clipboard before to run matlab.

This solution to run on XP-Matlab 6.0-pentium IV.

Test for atlon 2400+ and xp???

Re: matlab error

I have installed Service pack 1 and the problem is stopped
