Is it another command using to compare between vector and cell?

1 view (last 30 days)
I have this code bellow: when U = [] and has value after , S also the same initila by S = {},
I use IsContainedIn to compare between each value fo U and S, but it doesn't work, an error appear : "Input A of class double and input B of class cell must be cell arrays of character vectors, unless one is a character vector."
Could you please help me I 'm stuck in this step
for i=1:numel(U)
if ~IsContainedIn(U(i),S{p})
w1 = [w1 U(i)];

I ant to check each element of U exist in S, we notice that U is vector and S a cell

Then, to obtain the elements of U that doesn't exist in S, you can do:
U = [1,2,3];
S = {1,2};
w = U(~ismember(U,cell2mat(S)))
