If z is the vector , one has More generally, an n× n Hermitian matrix M is said to be positive definite if z*Mz is real and positive for all non-zero complex vectors z. Here z* denotes the conjugate transpose of z. 摘自:https://en.wikipedia.org/wiki/Positive_semidefinite_matrix ...
The positive definite(full-rank)matrices comprise the cone interior, while all singular positive semidefinite matrices(having at least oneeigenvalue)reside on the cone boundary. The only symmetric positive semidefinite matrix having alleigenvalues resides at the origin. ...

Is a(i) supposed to be a(j)? If you haven't otherwise set i to be an integer, it defaults to sqrt(-1), which cannot be used as an index. Same goes for j; check that it's an integer. Best practices in Matlab recommend avoiding i or j as i...
