*COMPUTES THE STIFFNESS BY DIVITING Y OVER X*
=============================================

Computes the stiffness curve by dividing each Y value by the corresponding X value (Y/X) for a given velocity curve. Use this transformer when you need to derive a velocity-normalized stiffness (force/displacement or similar ratio) from a raw curve.

     - Input velocity (or force/displacement) curve as a paired X-Y vector; each Y value will be divided by its corresponding X value to produce the stiffness ratio — leave null to skip computation.
