Thanks for the feedback. I will try out the suggestions.

Is it more more common to construct the global matrix (in sparse  
format) than have a linear operator that iterates over all the  
elements for each operator evaluation? I can see that storing the  
global matrix reduces the time per iteration, but that way also  
increases the memory usage.
