Dear M(?),
you could pack your matrices into a list or an environment and then
iterate through that, either using "for" and subset operator "[[" or
using the lapply / eapply functions.
And instead of looping it is sometimes more elegant to put what you want
to do with each of your matrices into a function and then repeatedly
call the function.
Also have a look at "get" for accessing objects e.g. in the global
workspace by their name.
Best wishes
Wolfgang
