Hello Hoon, If you really want to have everything contained in Matlab there are at least two options: (1) use fmincon/fminunc in combination with the API. The coordinates are optimization variables for fmincon and you use them to set the model (with markers) in the corresponding pose through the API...

Hi, I noticed something happening in the Hunt Crossley Model that I can't understand completely. I have an adapted gait9musc18 model with 2 spheres in both feet and a half space in the ground as contact geometries. I am running a forward simulation with this model giving it some (random) activations...

In order to do predictive simulations I want to build up a model from ground via the feet up to the torso. This means (in topology view) that I do have to create a loop (that comes together at the pelvis) and I will try it like James and Michael have suggested. I am now trying to understand how the ...
