My understanding is that this is what the initialsz parameter is for
in nc__create. See:
http://my.unidata.ucar.edu/content/software/netcdf/docs/netcdf-c/nc_005f_005fcreate.html#nc_005f_005fcreate
This is in the C interface, I'm not familiar with the MatLab
interface, perhaps it exposes nc_create but not nc__create.
Good luck!
