@mljs/collaborators this is only the array implementation, the idea is to extend it to matrix but for now I prefer to merge it now and see the rest later, I'm even thinking to publish in npm in order to use it for Savitsky-Golay and other ML packages

Can you put the whole output array in the tests ?
Something like:

it('Default test', function () {
        var data = [1, 2, 3, 4];
        var model = padArray(data);
        model.should.eql([0, 1, 2, 3, 4, 0]);
});

made a few comments but looks good !

👍 thank you!

no man thanks to you, the question is should I publish it now to NPM and put it in ML or should I wait until I finish the matrix part?

I think it should be published without waiting for Matrix

I agree
