Hi, I'm trying to solve a system of non linear equations using nsolve but I'm getting the error: "NameError: name 'DiracDelta' is not defined".
My system looks like this: [-1.0*L1*sign(w1) - 0.00037…

Hello Devs,
I have a question on how exactly the equations of motion are solved by PhysX.
The reason I'm interested in these details is a comparison between Matlab and the Games Engine Unity for r…
