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)];

end

Thanks

U is a vector

U = [1 2 3]

S = { 1 2 }

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

在 MATLAB Online 中打开

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)))
