Matrix multiplication and General Documentation

[anurupmitra]

Hi,
I'm probably being very silly somewhere but I can't figure out how to multiply 2 matrices. I tried this :

Algebrite.run('A=[[a,b],[c,d]]');
Algebrite.run('C=[[x],[y]]');
Algebrite.run('A*C')

and got this:

[[x],[y]] [[a,b],[c,d]]

That looks like the two different matrices have been output?

Also, it would be super if the documentation could reflect the current version on Github!

Thanks and Regards
Anurup

dot(A,C) should do the trick. Can't use * because the engine considers * always to be commutative, which dot product isn't. (In fact, actually, in your result the order of the matrices is switched). Closing this issue for now, feel free to re-open if you find further issues.
