The UDU factorization exists for symmetric indefinite matrices, but in our code, we want to maintain positive-semidefiniteness. Our Kalman filter's operations (performed on real numbers) would maintai…

The floating-base, mechanical system
M(q) dot(v) + C(q,v) v + g(q) = S tau
must comply with:
i) The mass matrix M is symmetric, positive definite;
ii) dot(M) - 2C must be skew-symmetric.
The poin…

AFAICS these two functions copy to freshly allocated storage so the names should not have a trailing !

I'm trying to implement a model [(all code and errors here)](https://gist.github.com/binarybana/4fbb4e6dfc5d30da234e) where each lambda is two dimensional (across i and j), and is distributed accordin…

Currently, `lu`, `chol`, `(\)`, etc. convert an `Array{Rational{Int64},2}` to `Array{Float64,2}` before doing any computation. These should actually compute the decompositions using rational arithmeti…
