[ncl-talk] a quick question about array in ncl

[Kyle Griffin]

What you are setting with the third parameter in new(...) is not initial
values, but rather the _FillValue setting. Please read the documentation
here:

https://www.ncl.ucar.edu/Document/Functions/Built-in/new.shtml

As a result, you are saying "missing value + 0.1 = missing_value" and then
telling it to display the missing value as 1. Now, even if you set a=1,
which is the proper way to initialize the variables with a single value
regardless of dimensions, all values are still listed as "missing" because
you've set 1 to be the value in the variable that represents  having no
data at any given location. Try this:

a=new(3,float)
b=(/.1,.2,.3)
a=1
print(a+b)

This should be good. Any other questions, please let the list know.
