Tecplot Equation Editor (Difference in Adjacent Points)

[dreamchaser]

Hello,

I want to know if I can use the tecplot alter equation editor to calculate the difference in adjacent points
in a vector. For example, lets say we have x and y coordinates.

In MATLAB, I use the built in diff function which gives the difference in distance between adjacent points as :

dx=diff(x)
dy=diff(y)

How can I do the same thing in tecplot? I'm thinking there is not a built in diff function.


Thanks for your input,
