Implicit differential equation for 2D musculoskeletal model : f(x,dx/dt,u) = 0 with implicit contact formulation. This is the source code for the MEX function gait2cd.mex32 The musculoskeletal model is documented in the file gait2dc_reference.odt The function documentation is in gait2dc.m. The model includes an accelerometer model.
