Re: Record array dimension

I was surprised to find out that when I read a field from file into a record array with format string "8f4" the corresponding field has dimension (1,8) and not (8,) that I would intuitively expect. Am I possibly spesifying the format incorrectly? If not, why is there an extra dimension?
The first dimension(s) in a record array is always referring to the number of "rows". So, if you have:
import numarray.records as rec r=rec.array(formats='f4', shape=8) r.field(0).shape (8,)
which will be what you might have expected. But if
r.rec.array(formats='8f4', shape=10) r.field(0).shape (10, 8)
I assume you have the shape=1, and that's why you get (1, 8) for the field shape. You can have complicated tables like: --> r=rec.array(formats='(4,5)f4', shape=(2,3)) --> r.field(0).shape (2, 3, 4, 5) So, the field shape always has the record array's shape as first dimension(s). JC Hsu
