Using mir to work with matrices

[drug via Digitalmars-d-learn]

It is not easy to understand what mir library one should use to work 
with matrices. mir-glas turns out unsupported now and I try to use 
mir-blas. I need to reimplement my Kalman filter version to use more 
high dimension matrix than 4x4 plus Kronecker product. Is mir-blas 
recommended to work with matrices?
