#### Issue Description
I'm in the process of adding ND4J to a Java linear algebra benchmark but I'm having trouble adding decompositions like, Cholesky, QR, SVD, Eigen, ... etc or solving for squar…

Hi,
In my application I have two traits where only a subset of the samples have observation on both traits. I want to use the kernel matrix for the samples to estimate the trait covariance components…

Currently transition matrices are being updated individually to resemble the
original PhyML code. In other words, UpdateTransitionMatrices() updates a
single matrix. Consider surgically extracti…

I have been using `CVXOPT` lately and have found it brilliant for individual sparse cholesky decompositions. However, I was just wondering if `CVXOPT` has any plans in vectorising/broadcasting operati…

Consider the following example:
```jl
P = @SMatrix [-0.5 0.5 0.5; 0.5 -0.5 0.5; 0.5 0.5 -0.5] # SMatrix{3,3,Float64,9}
w = rand(Float64, 3) # Vector{Float64}
W = rand(Float64, 3, 3) # Matrix{Fl…

Currently, both LU decomposition algorithms require the input matrix to be square. However, neither Matlab nor Eigen require square matrices for their full-pivot LU decompositions, and Golub and Van L…

I was surprised by this:
```julia
julia> sqrt(5.0I)
ERROR: MethodError: no method matching sqrt(::UniformScaling{Float64})
Closest candidates are:
sqrt(::Float16) at math.jl:1085
sqrt(::Comp…

Some thoughts about the structure of the library:
- sparse-traits: All interfaces and trait definitions
- sparse-core: Common sparse matrix implementations, vectors, etc. Essentially a minimum via…

The following matrix cannot be decomposed even though it is unitary.
```
U = np.matrix([[(-0.7108860402090058-0.7033072016973199j),
