This is actually run in the matlab environment
I have followed the prompts, but why does this problem still occur?
Is there something wrong with my nlp model? Because I found that only the constraint of the Y label was problematic, and the x label was not. But I don’t think that’s possible, because they all use the same set

1 constraint RELATIONSHIP_YM_large_cav[17,1]:
I found a question, does 17 represent the element in the set large_cav? I found that there is no element 17 in large_cav and Middle_cav, and even the elements in the above picture are not elements in large_cav and Middle_cav

ok ,thanks I’ve solved the problem
