function inputblks = trace_mux_network(dstblk,dstport)

% Find handles and order of muxed input blocks

% Syntax:
%   "inputblks = trace_mux_network(dstblk,dstport)"

% Description:
%   "trace_mux_network(dstblk,dstport)" returns, in order, the input
%   blocks that are muxed together before feeding into the destination
%   port "dstport" of the destination block "dstblk".
