Computes the cross product between two numeric arrays.
$ npm install compute-crossFor use in the browser, use browserify.
To use the module,
var cross = require( 'compute-cross' );Computes the cross product between two numeric arrays.
var arr = cross( [1,2,3], [4,5,6] );
// returns [ -3, 6, -3 ]Note: both arrays must be length 3.
var cross = require( 'compute-cross' );
// Parallel vectors:
console.log( cross( [1,-2,3], [2,-4,6] ) );
// returns [ 0, 0, 0 ]
// Anti-parallel vectors:
console.log( cross( [-1,2,-3], [2,-4,6] ) );
// returns [ 0, 0, 0 ]
// Non-parallel vectors:
console.log( cross( [4,-2,1], [1,-1,3] ) );
// returns [ -5, -11, -2 ]To run the example code from the top-level application directory,
