n-dimensional vector magnitude
MIT License
2D, 3D and n-dimensional vector magnitude.
var magnitude = require('magnitude')
magnitude([ 0, 1, 0 ])
//=> 1
magnitude([ 0, 4, -3 ])
//=> 5
Or the squared magnitude (to avoid a sqrt
operation).
var magSqr = require('magnitude/squared')
magSqr([ 0, 4, -3 ])
//=> 25
npm install magnitude --save
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.
