# Description

Multiplies the joint stiffness of a particular joint by a specified value.

It multiplies the internal covariance matrix and then updates the per-axis stiffness values of a specific joint to reflect the new matrix values. For example, if you have just calibrated and think the joint stiffness for a specific joint needs to be altered for optimal labeling, instead of capturing a whole new ROM, you can just use multiplyJointStiffness to adjust the stiffness for that joint.
