@rafaelmaeuer Have you been able to fix the issue?

Facing the error for custom-generated SDF

Download and add https://github.com/HybridRobotics/geometric-toolbox to your path. You can also replace it with `cross` the Matlab's [cross](https://www.mathworks.com/help/matlab/ref/cross.html)

You are trying to use the`mex` files. You need to first generate the mex files to use them. In the meantime I would recommend setting the dynamics to default, `params.dynamics...

As the name suggests its the mexed function for [getNormDerivatives14.m](https://github.com/HybridRobotics/multiple-quadrotor-flexible-hose/blob/master/matlab/utils/func_generators/getNormDerivatives14.m), either replace `getNormDerivatives14_mex` with `getNormDerivatives14` (i.e. don't use the mexed function), or generate the mex function for `getNormDerivatives14.m`
