How to vectorize this nested for loop?

Hi everyone, I want to vectorize this nested for loop with an 'if' condition. Could you please let me know how to get it done?

b=0;
pair = [];
min1 = 1;
max1 = 1;
for n = -min1:max1
    for m = -min1:max1
                if n+m == b
                    pair = [pair;n,m];
                end
    end
end

%Original Approach
b=0;
min1 = 1;
max1 = 1;

pair = [];
for n = -min1:max1
    for m = -min1:max1
                if n+m == b
                    pair = [pair;n,m];
                end
    end
end


pair

pair = 3×2

-1 1 0 0 1 -1

%Vectorized approach
[n,m] = meshgrid(-min1:max1)

n = 3×3

-1 0 1 -1 0 1 -1 0 1

m = 3×3

-1 -1 -1 0 0 0 1 1 1

idx = n+m==b

idx = 3×3 logical array
   0   0   1
   0   1   0
   1   0   0

out = [n(idx) m(idx)]

out = 3×2

-1 1 0 0 1 -1
