x

t = [1,2,3,4];
c = [1;2;3];
r = [1,2,3,4];
n = [1:12];

T = length(t);
C = length(c);
R = length(r);
N = length(n);

X = binvar(N,R,C,T,'full');
constraint  = [];
for h=1
for i = 1:N;
      conn = 0;
      for c = 1:C
         for  r = 1:R
            X_irch = value(X(i,r,c,h))       %  这个值为什么会是NaN
            if X_irch == 1
               P(r,c,h) = 1;
            end
            conn = conn + X(i,r,c,h);
         end
      end
      constraint = constraint + [conn == 1];
end
end

有注释的那一行的值为什么会是NaN，不是应该取值为0或者1吗？请教大神！
