Hi every body,
I have a dataset excel CSV sheet with a three columns,(X,Y, and Z)
The first and second columns represents the coordinates of point, while the third one represents the elevations value of the point.
What i need is to subtract the first row from the second one and the second row from the third and the fourth from the fifth and the fifth from the sixth ….. etc. till the end of the data
The output should be saved on a fourth column (say output column)
And finally all the datasets to be saved to an excel file
Thanks A lot,

Use readtable(), diff() and finally writetable().
