I would like some help with coverting a matrix that is generated randomly to a binary matrix

This is a distance matrix which generates random number for every iteration. Is it possible to generate a binary matrix which has ones in place of the lowest 2 values in each row and zeros everywhere else? Can i please get some help with that?

d = rand(4,4)          % random data 

d = 4×4

0.3227 0.2997 0.6497 0.7723 0.2227 0.7284 0.6703 0.8356 0.3157 0.4773 0.7145 0.0510 0.4854 0.4051 0.6248 0.5357

y = zeros(size(d));
for i=1:size(d, 1)
    [~, idx] = sort(d(i, :));  % sort in asencing order 
    y(i, idx(1:2)) = 1;
end
y

y = 4×4

1 1 0 0 1 0 1 0 1 0 0 1 1 1 0 0
