This is a heads up to anyone using the convenient GMatrix class. When you are working in say Finite Elements and you want a nice matrix construct that you can reduce (GMatrix.setSize(int int)), GMatrix for some reason uses huge amounts of memory to run this method. Maybe someone at Sun can work on getting this operation to be a bit more efficient. I tracked the free memory in the virtual machine when using this method and it will roughly cut the free memory in the virtual machine in half. It seems to be equivalent to defining a new GMatrix object of the new size and then keeping both objects in memory. If this is the case then it's pretty pointless to have that method at all. If anyone has a suggestion please help!
