magnitude
2D, 3D and n-dimensional vector magnitude.
Example
var magnitude = //=> 1 //=> 5
Or the squared magnitude (to avoid a sqrt
operation).
var magSqr = //=> 25
Install
npm install magnitude --save
Usage
len = require('magnitude')(vector)
Returns the vector magnitude of the given n-dimensional vector array.
lenSqr = require('magnitude/squared')(vector)
The same as above, but without the final Math.sqrt
operation.
