Root LP problem is unbounded. Intlinprog stopped because the root LP problem is unbounded.

回答: 根据您提供的引用内容，当出现"Root LP problem is unbounded"的错误时，这意味着根线性规划问题是无界的。这可能是由于您在使用intlinprog函数时没有正确指定上下限导致的。正确的写法应该是x=intlinprog(z,\[1:50\],a,b,aeq,beq,lb,ub)。\[1\]请确保在使用intlinprog函数时，正确地指定了问题的约束条件和变量的上下限，以避免出现无界问题。
