% Suppose I have a cellarray
C = {[1; 2; 3]; [1; 2; 3; 4]; [4; 1; 2; 3]; [1; 2]};
c{:}
ans =

ans =

% where any digit won't repeat in the individual cell.
% I need to find out: how many times a particular sequence is present inside the cell array.
Expected output:
sequence_check = {[1; 2; 3]}
Number_Of_Times_that_sequence_is_Present_Inside_the_Cell_Array = 3
Show_the_index_of_those_cells = 1 2 3

C = {[1; 2; 3]; [1; 2; 3; 4]; [4; 1; 2; 3]; [1; 2]};
sequence_check = [1; 2; 3];
n = sum(cellfun(@(x) ~isempty(strfind(x.',sequence_check.')), C))
