Re: implicit loop.Reading of data

["Pavel A. Romashkin" <pavel.romashkin(at)noaa.gov>]

Try reading all data into a vector:

a = fltarr(15)
openr, unit, 'myfile.dat', /get_lun
readf, unit, a
free_lun, unit
result = transpose(reform(a, 3, 5))

the above example uses your data layout (3 arrays of 5 elements each).
RESULT is a 5 x 3 array, optimized for rowwise operation (each of your
arrays can ba accessed as Result[*, i].

Cheers,
Pavel
