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.

Ran in:
Did you try to google the documentation for the ismember function?
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
end
sum_coord=sort(sum_coord);
sum_coord=unique(sum_coord);
disp(sum_coord)
1 2 3
L=ismember(target,sum_coord);
ismissing=target( ~L );
disp(ismissing)
