pytransform3d.rotations.check_rot_log#
- pytransform3d.rotations.check_rot_log(V, tolerance=1e-06, strict_check=True)#
Input validation of a skew-symmetric matrix.
Check whether the transpose of the matrix is its negative:
\[V^T = -V\]- Parameters:
- Varray-like, shape (3, 3)
Cross-product matrix
- tolerancefloat, optional (default: 1e-6)
Tolerance threshold for checks.
- strict_checkbool, optional (default: True)
Raise a ValueError if V.T is not numerically close enough to -V. Otherwise we print a warning.
- Returns:
- Varray, shape (3, 3)
Validated cross-product matrix
- Raises:
- ValueError
If input is invalid
