I want to check that the Value of one array exist in another array, using function ?

RemainingSensor=[1 2 4];
Cover=[1 3];
[m,n]=size(RemainingSensor);

for i=1:m
    for j=1:n
        r=RemainingSensor(i,j);
        a=funcCover(r);
         display(a);
    end
end

function c= funcCover(v)
[s,t]=size(Cover);
    for i1=1:s
        for j1=1:t
            k=Cover(i1,j1);
            if k==v
                c=k;
            end
        end
    end
end

first array is "RemainingSensor" and wants to check that the of this sensor existe in other array that is "Cover", how it is possible?

Answer 1

[Johannes Hougaard]

It is possible using the function ismember

RemainingSensor=[1 2 4];
Cover=[1 3];
validsensors = ismember(RemainingSensor,Cover);

I wants to use function?

[Johannes Hougaard]

ismember is a function that is a part of MATLAB

[Aqeel Awan]

Yeah, i know but I want to do this with above scenario, that i've uploaded

[Johannes Hougaard]

Then I'd just use funcCover as a function calling ismember.

Regardless of what you do you'll have to have two inputs to your function, as your variable 'Cover' is never sent to your function funcCover as long as it only have one input.

RemainingSensor=[1 2 4];
Cover=[1 3];
[m,n]=size(RemainingSensor);
for i=1:m
    for j=1:n
        r=RemainingSensor(i,j);
        a=funcCover(r,Cover);
         display(a);
    end
end
function c= funcCover(v,W)
    if ismember(v,W)
        c = v;
    else
        c = 0;
    end
end
