Sorry, this need "global E1" inside the function body.

I wonder if you found a memory leak. Can you tell me if just

  for i=1:100
    load E1.csv
  endfor

makes your memory usage grow without bound? It doesn't seem to in the
dev sources, so perhaps it's an old memory leak that was patched since
3.2.4
