function [s] = gsp_jtv_filter_inverse(G, filter, filtertype,c, param)
%GSP_JTV_FILTER_INVERSE Inverse operator of a joint timve_vertex filterbank
% Usage: s = gsp_jtv_filter_inverse(G, filter, c);
% s = gsp_jtv_filter_inverse(G, filter, c, param);
%
% Input parameters:
% G : Time-vertex Graph structure.
% filter : Cell array of time-vertex filters.
% filtertype : Filter domain (ts,js,ts-array,js-array)
% c : Transform coefficients
% param : Optional parameter
% Output parameters:
% signal : sythesis signal
