Sorts ndarrays in place


Sorts ndarrays in place using a dual pivot quick sort.

var ndarray = require("ndarray")
var ndsort = require("ndarray-sort")
var unpack = require("ndarray-unpack")
//Create an array 
var x = ndarray(new Float32Array(60), [20, 3])
for(var i=0; i<20; ++i) {
  for(var j=0; j<3; ++j) {
    x.set(i,j, Math.random())
//Print out x: 
console.log("Unsorted:", unpack(x))
//Sort x 
//Print out sorted x: 
console.log("Sorted:", unpack(x))
npm install ndarray-sort

Sorts the given array along the first axis in lexicographic order. The sorting is done in place.
