Suppose i have an array as,
A={ [2,3;2,7] [3,2;3,4;3,8] [4,3;4,5] [5,4;5,10] [7,2;7,8;7,12] }
and a matrix as B=[17,8,14,4,18]
now i want to match the element from B with A and want answer as
C={ [ ] [3,4 ; 3,8] [4] [5,4] [7,8] }
plz help

A general hint: The cell array contains matrices, which consist of numbers. Explain problem in the terms Matlab can work with. "routes" and "nodes" are the meaning of the numbers, but this does not matter for Matlab, so it does not for solving the problem.
There is no need for apologies: It is a standard step in solving a problem to ask questions for clarifications. Your question about Matlab are welcome here.

A = {[2,3;2,7], [3,2;3,4;3,8], [4,3;4,5], [5,4;5,10], [7,2;7,8;7,12]};
B = [17,8,14,4,18]
C = cell(size(A));
for iA = 1:numel(A)
a = A{iA};
match = any(ismember(a, B), 2);
if any(match)
C{iA} = a(match, :);
end
end
celldisp(C)
% C={ [ ] [3,4 ; 3,8] [4] [5,4] [7,8] }
