How to control arm26 models from matlab

Dear all

I want to control an OpenSim arm26 model from matlab.

So, is there any command to assign the calculated value of muscle tension to the arm26 model?

Best regards

About the arm26 model simulation

Dear all I want to simulate an arm26 model in Matlab. However, there are two things I do not understand in doing so. The first is the conditions under which the muscles wrap around the shoulder and elbow joints when deriving the muscle length function. The second is the function after the muscles ar...

Re: Muscle length in the upper limb model (arm26)

Sorry for the late reply.

Thanks to you, I was able to derive the muscle length function by reducing it to a quadratic plane for now.

Next, I will extend it to 3 dimensions.

Thank you very much.

Re: Muscle length in the upper limb model (arm26)

Thank you for your reply.
The length of the muscle changes as the joint angle changes, but what formula is used to output this?

Muscle length in the upper limb model (arm26)

I would like to derive the length of each muscle (TRIlong, TRIlat, TRImed, BIClong, BICshort, BRA) in the upper limb model (arm26.osim) as a function of the shoulder and elbow joints when they are moved. How do you derive the muscle length for each joint angle in OpneSim?
