Compute the Jacobian matrix, J, for a given joint configuration. The manipulability measure is w = √det(J * J'). Iterate this calculation across the robot's workspace. In MATLAB, use the `sqrt(det(J*J'))` function within a loop over joint angles, then plot the result (e.g., via `scatter3` or `contour`) to visualize its variation.
