Calculate pupil speed using finite differences

Description

Computes the speed of pupil changes using finite differences between consecutive time points. This is a helper function for the detransient step.

Usage

speed(x, y)

Arguments

x	A numeric vector of pupil data
y	A numeric vector of time data

Value

A vector of pupil speeds at each time point
