Calculate gradient [message #70086]

Hi IDL experts,
I have a 2-D array (2708x4060), containing reflectance data. Is it
possible to calculate the reflectance gradient (i.e. the rate of
reflectance change over distance or array grid) throughout the array,
and then draw lines of equal gradient (note that they’re NOT contour
lines)?
Thank you very much for your help!
IDL beginner
