The epitaxy matrix, as given in the work quoted above, reads: +```math ( px, qy ) ( qx, py ) - +``` with: +```math px=b1*sin(alpha-theta)/(a1*sin(alpha)) qx=b2*sin(alpha-theta-beta)/(a1*sin(alpha)) qy=b1*sin(theta)/(a2*sin(alpha)) py=b2*sin(theta+beta)/(a2*sin(alpha)) - +``` There are two reasons for the length of this program: o) asin isn't unique. o) ranges of angles are a pain to deal with. |
