ndarray-normalize

ndarray-normalize

Normalizes an ndarray so that the mean is 0 and the standard deviation is 1.

Example

var moments = require("ndarray-moments")
var lena = require("luminance")(require("lena"))
 
console.log("Before normalization:", moments(2, lena))
 
require("ndarray-normalize")(lena)
 
console.log("After normalization:", moments(2, lena))

This prints out:

Before normalization: [ 124.04670674515125, 17677.59913617722 ]
After normalization: [ -7.130396703039932e-14, 1.0000000000002789 ]

Install

npm install ndarray-normalize

require("ndarray-normalize")(output, input)

Normalizes an ndarray

  • output gets the result
  • input is the array that gets normalized (if unspecified, output is normalized in place)

Returns output
