[jitter] Problems with speed of patch using Expr and Matrix

Okay, I've looked at my patch again and it is not the 'virtual sand' that I orignally thought was the problem. 

[img]index.php?t=getfile&id=777&private=0[/img]

I have 20 or so formula's in a java external. They are selected using values, n and m in inlet 2 and 3 - no processing at all. The selected formula is passed out of the outlet into jit.expr. As the formula is be passed into jit.expr it starts a bang, where a new matrix is also passed into jit.expr. If I scroll through the values n/m I get lots of slow down! I'm sure it has something to do with creating a new matrix for each expr! Though I dont know a better approach? Any ideas?

Thanks.
