MATLAB: I want to compare two arrays and check that which value is missing in second array as compared to first one

compare arrays

A=[ 0 1 1 ;
    1 1 0 ];
target=[1 2 3 4];
[m,n]=size(A);
c1=0;cover1=[];sum_coord=[];sss=0;
for i=1:m    
    cc=0;t_coordinate=[];
    for j=1:n          
            if A(i,j)==1            
                cc=cc+1;
                t_coordinate(cc,:)=j;
                sss=sss+1;
                sum_coord(sss,:)=t_coordinate(cc,:);
            end     
    end    
    display(t_coordinate)
end
sum_coord=sort(sum_coord);
sum_coord=unique(sum_coord);
display(sum_coord)
first array is "Target" and second is "sum_coord"….

You should avoid variable names like sum, as that will prevent you from using the sum function.
Your question sounds like you need the ismember function. However, it is unclear how your code relates to the question in the title.
