Bacon and Eggs:
Bacon and Eggs is a simple linear algebra library written entirely in javascript. More of a proof of concept than anything else, it allows for easy representation of matrices and vectors. On top of that it can solve systems of equations!
Heres a simple example of what bacon and eggs can do:
//define a new matrix 'A' representing
// [1,-4]
// [1, 2]
var A = $M([[1,-4],[1,2]]);
//define a new Vector 'b' representing
// [1,-2]
var b = $V([1,-2]);
//Solve the system!
// x - 4y = 1
// x + 2y = -2
var Solution = A.solve(b);
//returning a vector representing
// x = -1, y = -1/2
// [-1, -0.5]
//find the length of the solution vector
//from the origin for some reason!
var length = Solution.length();
To see more of what Bacon and Eggs can do, make sure you check out the full documentation.
It should be noted that Bacon and Eggs has not been optimized for speed. It was designed merely as a way to experiment with linear algebra algorithms. If you are looking for something that has been optimized, say for graphics purposes, I highly recommend you check out Sylvester by James Coglan.

Frequently Asked Questions:
• What is Bacon and Eggs good for?
A couple of things. Firstly, its pretty darn good at solving systems of equations. Secondly you can do some rather complex calculations on matrices and vectors. And lastly, if you're interested in seeing how some mathematical algorithms are implemented, you can look through the source code to see how things actually work.
• You say Bacon and Eggs has not be optimized, what do you mean?
I mean that I haven't gone through trying squeeze every cycle to do the most it possibly can. I just really don't want people going through the source code saying, "Why haven't you replaced your for loops with do while loops?", "Why are you using so many variables?", "I see a bunch of unnecessary looping going on, whats up with that?" It does what I want it to do, and if that works for you too great, if not, I'm sorry, but maybe there is something else that will work for you.
• Do you ever plan on optimizing Bacon and Eggs?
I don't think so, no. I set out to try my hand at programming some concepts I learned in a numerical methods course. Thats all. I never wanted to make this into some gung ho library that would blow peoples minds.
• Why did you create Bacon and Eggs?
I remember back in my early days of computing science, when I first started learning to program, thinking to myself, 'Gee golly, wouldn't it be neat to write something to do my linear algebra homework?' It wasn't until a couple years later I took an intro course on numerical methods, in it we were taught how to do many of the things I dreamed of doing in my first year. So Bacon and Eggs is really just an implementation of something I had dreamt of years earlier.
