Hi Eli,

if your goal really is to just create the 10x8 array via the loop and
then print the complete array, I wouldn't use pointers. A simple

arr = fltarr(10,8)
for i = 0,9 do begin
...
arr[i,*] = (some 1 by 8 vector)
endfor

print, arr

will do the trick.

If you _really_ want to use the pointer array, you have to manually
concatenate the individual vectors like

print, transpose([[*ptr[0]], [*ptr[1]], ..., [*ptr[9]]])

which is far from being elegant and most likely will waste some memory.
Not really a problem with 10x8 entries, but there is probably more to
come?

While you think over it, why not completely re-thinking the problem and
trying to avoid the for-loop at all :-) ?

Cheers,

Peter
