% INDEX.ADD_DOF
%--------------------------------------------------------------------------
% Add degrees of freedom to the system

%--------------------------------------------------------------------------
% Syntax
%--------------------------------------------------------------------------
[IN,new_num] = ADD_DOF(IN,loc_dof,cur_node)
[IN,new_num] = INDEX.ADD_DOF(IN,loc_dof,cur_node)

%--------------------------------------------------------------------------
% Description
%--------------------------------------------------------------------------
% INDEX.ADD_DOF allows to update the indexation table when adding new
% degrees of freedom in the system. This method is used when applying
% Dirichlet boundary conditions for instance.

%--------------------------------------------------------------------------
% Input arguments
%--------------------------------------------------------------------------
% IN          : INDEX object
% loc_dof     : local number of degrees of freedom (type)
% cur_node    : set of NODE objects

%--------------------------------------------------------------------------
% Output arguments
%--------------------------------------------------------------------------
% IN          : INDEX object - updated object
% new_num     : scalar - updated number of degrees of freedom

%--------------------------------------------------------------------------
% Example
%--------------------------------------------------------------------------
[IN,new_num] = ADD_DOF(IN,loc_dof,cur_node)
