Finds all zero crossings in a 1D ndarray

zero-crossings

Finds all zero crossings in a 1D ndarray assuming piecewise-linear interpolation.

Example

var ndarray = require("ndarray")
var zc = require("zero-crossings")

var array = ndarray([1, -1, 0, 10, 3, -1])

console.log(zc(array))

Output:

[ 0.5, 2, 4.75 ]

Install

npm install zero-crossings

API

require("zero-crossings")(array[,level])

Finds all zero crossings in the 1D ndarray array

• array is a 1D ndarray
• level is an optional parameter which indicates the crossings

Returns A list of all zero crossings in array
