zerocrossing function

Zero Crossing

Estimate zero crossing points of waveform.

zerocrossing(x, y)

Arguments

• x: the x-coordinates of points in the function.
• y: the y-coordinates of points in the function.

Returns

Zero-crossing points

Examples

x <- seq(0, 1, length.out = 100)
y <- runif(100) - 0.5
x0 <- zerocrossing(x, y)
plot(x, y, type ="l", xlab = "", ylab = "")
points(x0, rep(0, length(x0)), col = "red")
