Clairekun	Posted - 07/14/2020 : 6:18:41 PM Origin Ver. and Service Release (Select Help-->About Origin): 2018b Operating System: Windows 10 Hello, I would need to create a column with the formula -dy/dx, smoothed via adjacent-averaging method. Is there any way to achieve this that wouldn't require me to add 3 extra columns each time (one for dy/dx, a second one for changing previous column sign and a third one for smoothing)? My worksheets already contain multiple columns and I would like to avoid creating any unnecessary ones. I am using differentiate function since derivative function is no longer recommended, but the options are very limited. Thank you.
