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'stempsum... Also, perhaps list the version numbers of the packages and software you're using...

No problem, but bear in mind that the more tasks the prospective answerers have to do, the fewer of them will be prepared to do them all. :)
