Detailed Description

contains a {{x11,x12},{x21,x22}} set, a (3x3) structure, and a (d x d) structure (and matrix manipulations)

Matrix2x2 provides a simple interface for operations using 2x2 matrices. In particular, it implement matrix-maxtrix multiplication, and has specialized matrix-vector and vector-matrix multiplication in which scalar2 variables take the place of vectors. A dyadic product is implemented which takes two scalar2s and returns a Matrix2x2
