Re: str_get_field

Hi Wen,

The colons give options for how to subscript each dimension of your
variable. The colons allow you to subset the data such that:

var(min:max:stride)

and leaving any one of the places between the colons blank results in the
default choice for that setting (which is to be from the beginning to end
of the data by 1's, or every point)

You can read more on subscripting at:
