Working on https://github.com/robotology/mex-wholebodymodel/issues/30 ... the two forwardDynamics_zeroExternalForces.m
are quite different.. From the return values I will assume that the one in the root folder (https://github.com/robotology/mex-wholebodymodel/blob/master/forwardDynamics_zeroExternalForces.m) is the one used by the kinetic energy test.. moving it to tests directory and changint its name.
capito! this came because of multiple developments on top of my original forwardDynamics. Addressing soon.

I repeat: NEVER EVER EVER [1] use the same name for two different matlab files, even if they are in two different folders.
Examples of duplicates files (tick when solved):
- forwardDynamics.m (this is one is tragic because the different versions have totally different semantic meaning)
- integrateForwardDynamics.m
- forwardDynamics_zeroExternalForces.m

Actually the one in the root is just an outdated version, the real version of forwardDynamics_zeroExternalForce
is of https://github.com/robotology/mex-wholebodymodel/blob/master/forwardDynamics_zeroExternalForces.m .
In any case, both version should just be calls of forwardDynamics with zero input torques and null constraint list, see https://github.com/robotology/mex-wholebodymodel/issues/42 .
I think that sometimes having the same name for different files may make sense. For instance, in
we use several matlab files called
gains.m
associated with each robot, which contains the gains for the torqueBalancing. This is reminiscent of what we do with the torqueBalancing.c++. Opinions?
Agreed [1], mostly because those are more configuration file in matlab syntax than actual scripts.
There are also other situations where it may be convenient to have two function with the same signature/name, in that case I think they should be placed in different packages.
[1] :+1: (Perhaps NEVER EVER EVER can become NEVER EVER SOMETIMES :D ).
Isnt this addressed in https://github.com/robotology/mex-wholebodymodel/pull/49?
Not all of them, there are still three forwardDynamics, two integrateForwardDynamics, etc etc.
fixed in branch feature/torques_linear
