Because I want to write the LANDUSEF to a nc file, so I would like use the dimension name.
And it works well when i follow you method. thanks.

I know we can use "delete(landusef)" to decimate the variable,or use :: to reduce the lenth,
but what i want to do is to change the data lenth in a nc file. I tried to modify the variable
in the file by "fnc->landusef=landusef(:,0:50)", it tells me the dimetion is not equal between
the left side and the right side.
