We have a gray image I, and we need to create a function F(I,a,b) to return a binary matrix F that is of the same size as I, where 1 for pixels satisfying the domain condition and 0 otherwise. a and b means the domain [a, b].

You can use below attached code as a reference

function I=F(I,a,b)
 [c, d]=size(I);
for i=1:c
    for j=1:d
        if(a<=I(i,j)&&I(i,j)<=b)
            I(i,j)=1;
        else
            I(i,j)=0;
        end
    end
end
end
