getJointPos.m

function jointPos = getJointPos(KinDynModel)

    % GETJOINTPOS retrieves the joints configuration from the reduced model.
    %
    % This matlab function wraps a functionality of the iDyntree library.

    % FORMAT:  jointPos = getJointPos(KinDynModel)
    %
    % INPUTS:  - KinDynModel: a structure containing the loaded model and additional info.
    %
    % OUTPUTS: - jointPos: [ndof x 1] vector of joint positions.
