Quick array question [message #21687] Wed, 13 September 2000 00:00

Hi All

How does IDL store arrays in memory, does it use c style ordering or fortran
style ordering?

Here's my problem, I wrote a fortran program that writes a binary file to
disk with an array (nx,ny,nz). Now when I read that file should I do

data = fltarr(nx,ny,nz)
readu, unit, data

or should I do

data = fltarr(nz,ny,nx)
readu, unit, data

and convert it later?

Thanks in advance, Ricardo
