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

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

end

Thanks

Is IsContainedIn a native MATLAB function? I'm having trouble finding it.

No it isn't

it a function using in genetic algorithm,

it is better to find a matlab function do the same thing as IsContainedIn

[Daniel M]

Right. Well, I'm not sure what you're storing in U and S, but have a look at ismember and strcmp

[Alex Mcaulley]

What is the content of S and U? Are you trying to merge S and U without repetitions?

[Mira le]

U is a vector

U = [1 2 3]

S = { 1 2 }

[Mira le]

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)))

Thank you so much it works
