New version

In principle the same, but the original shorten IC's are used, a single twitch is executed and the value after 2000ms is used as initial condition.

% Usage The resulting "coeff" matrix is stored in the models.motorunit package folder as x0coeff.mat and read upon model construction.

function models.motorunit.experiments.SarcoScaling

(

)

Script to create an output force scaling for the Shorten sarcomere model. The assumption is to have the same force being generated from each fibre type when only one twitch is performed.

This is still questionable!

The resulting polynomial coefficients are stored in the models.motorunit.SHSystem.ForceOutputScalingPolyCoeff property and used for appropriate scaling of the output signal (depending on the fibre type)
