PURPOSE

determine the order of the symmetry operator

SYNOPSIS

function N = sw_symorder(R, T)

DESCRIPTION

 determine the order of the symmetry operator

 N = SW_SYMORDER(R, T) 

 It determines the order of the (R,T) symmetry operator, where R is a
 rotation matrix and T is a translation. Maximum order is 10 if the matrix
 is not a rotation matrix of any crystallographic point group.

 Input:

 R         Rotation matrix, dimensions are [3 3].
 T         Translation vector, dimensions are [3 1] optional.

 Example:

 R^sw_symorder(R) == eye(3);
