swsym.oporder

Syntax

N = swsym.oporder(symOp)

Description

N = swsym.oporder(symOp) determines the order of the symOp symmetry operator, where symOp(:,1:3) is a rotation matrix and symOp(:,4) is a translation. The value of 10 is returned if the matrix is not a valid crystallographic symmetry operator.

Examples

Raising any operator to the calculated order will alway return identity:

O = swsym.generator('y,z,x')

Output

O =
     0     1     0     0
     0     0     1     0
     1     0     0     0

R = O(:,1:3)^swsym.oporder(O)

Output

R =
     1     0     0
     0     1     0
     0     0     1

Input Arguments

symOp

Symmetry operator in a matrix with dimensions of $[3\times 4]$.

Output Arguments

N

Integer, the order of the operator.
