comment Why does Outer sometimes return a packed array, and sometimes not?
@xzczd Well, on the contraray, I would call "dividing it into 2 or 3" as scattered : ), and I suffered a lot from scattered questions when searching solutions on SE site. I organized them together, because all of them generate the same list, and they are what one can think of when dealing this kind of problem (I mean calculating data on a mesh)

also I have pasted a complex version of my original real version of Inverse. I find it the data exchange part is really cumbersome. I am not sure whether I have written something unnecessary or not, could you please have a look at it?

Thank you so much, Szabolcs. You've helped me a lot in my learning of librarylink! In terms of reintrepret_cast, I suppose it should not have overhead, just reinteprete of data, right?

@Szabolcs I don't understand. In C99, the complex number is defined by macro gnu.org/software/libc/manual/html_node/Complex-Numbers.html It is not the same as mathematica's mcomplex, is mcomplex also a standard?

@Szabolcs Hi, szabolcs. OK, I will if the code getting larger. But what do you mean by "identical to mcomplex", and how to use reinterpret_cast
