function judge = TestIfSE3(mat)
% *** CHAPTER 3: RIGID-BODY MOTIONS ***
% Takes mat: A 4x4 matrix.
% Check if mat is close to or on the manifold SE(3).
% Example Inputs:
%
% clear; clc;
% mat = [1.0, 0.0, 0.0, 1.2;
% 0.0, 0.1, -0.95, 1.5;
% 0.0, 1.0, 0.1, -0.9;
% 0.0, 0.0, 0.1, 0.98];
% judge = TestIfSE3(mat)
%
% Output:
% judge =
% 0
judge = norm(DistanceToSE3(mat)) < 1e-3;
