The error occurs on @NLobjective(m, Min, tempsum), but I dont know how to modify the code. May you please anyone help me ?



Besides, I am also confused by how to add positive definite contraints here for the solution Matrix aij, as I want to get a positive definite matrix aij.

  • Hi Ryan. In questions it's best to use simple data rather than CSV files, since no-one has access to those. Is the problem still there if you replace all these with a few simple numbers? (This is the MWE approach.) Then people can copy/paste your code. The error suggests that one of the arguments isn't the right form; at a guess, it's tempsum... Also, perhaps list the version numbers of the packages and software you're using...
