Computes the cross product between two numeric arrays.
$ npm install compute-crossFor use in the browser, use browserify.
To use the module,
varcross=require('compute-cross');Computes the cross product between two numeric arrays.
vararr=cross([1,2,3],[4,5,6]);// returns [ -3, 6, -3 ]Note: both arrays must be length 3.
varcross=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,
