Not know anything about your problem, I'd suggest to try to think  
about your problem in terms of storing these matrices in a list. For  
example, assume you have matrices m1 to m10

my.stuff <- list(m1, m2, ..., m10)

If you can elaborate more on your specific case (or perhaps a simpler  
one that can demonstrate your use case), perhaps we can help you think  
it through a bit.
