Re: Weird error from contributed...

Hi Erick,
Whenever you see an error message with the word "Malloc" in it it
usually means that you are running out of memory. First thing to try
would be deleting the u array after you create uAvg. If that doesn't
free up enough space Iwould try reading in u, and then dim_avg_n_Wrap
it, delete(u), and then repeat for v. Adam
