Re: eof hints, please
Hi Bob,
Try it this way: Do not set the region with SET REGION,
but with a qualifier on the variable itself:
LET eof_xyfcn = eof_space(temperature[X=208:260,Y=-10.0:16.0,Z=10], 0.5)
This prevents any ambiguity in the region that the function uses,
and is always good practice when you are calling a grid-changing
function like the EOF functions. I will do more testing on what may
be occurring when these functions are used on a four dimensional
variable.
