Small size linear solver
Solve multiple (2x2) or (3x3) linear systems:
A(:,:,k)*X(:,:,k) = B(:,:,k) for k=1,2,...,N
The method used here is basic cofactor/determinant.
DISADVANTAGE: This method may be less accurate than Matlab backslash (using in for-loop) when the matrices are ill-conditioned.
ADVANTAGE: for a large number of systems - the speed-up is about 15-30 fold.
