Phoebe:
By definition, an orthogonal matrix is a square matrix whose columns are
orthonormal; i.e., if v[i] and v[j] are the ith and jth columns of the
square matrix M, and if the dot product satisfies:
v[i]*v[j] = 0 if i <> j
v[i]*v[j] = 1 if i == j
then M is an orthogonal matrix.
A typical example of an orthogonal rotation matrix is the matrix which
specifies rotation of angle r about the z axis:
.cos(r)..sin(r)..0
-sin(r)..cos(r)..0
...0......0......1
I don't understand the question "where can I get the orthogonal matrix?"
What orthogonal matrix? What are you trying to do?
