function frameVelRepr = getFrameVelocityRepresentation(KinDynModel)

    % GETFRAMEVELOCITYREPRESENTATION retrieves the current frame velocity
    %                                representation.
    %
    % This matlab function wraps a functionality of the iDyntree library.

    %
    % FORMAT:  frameVelRepr = getFrameVelocityRepresentation(KinDynModel)
    %
    % INPUTS:  - KinDynModel: a structure containing the loaded model and additional info.
    %
    % OUTPUTS: - frameVelRepr: a string with one of the following possible values:
    %                          'mixed', 'body', 'inertial';
    %
    % Possible frame velocity representations:
    %
    %  0 = INERTIAL_FIXED_REPRESENTATION
    %
    %  1 = BODY_FIXED_REPRESENTATION
    %
    %  2 = MIXED_REPRESENTATION
