How can I rotate an eigenvector (complex) to make it real?

Hi,

There is any function in Matlab to rotate a vector/eigenvector to make it real?

Thanks

Define what you mean by rotate. Given a vector of length 10, with complex elements, what does it mean to "rotate" that vector? Even for a vector of length 2, what do you mean? Give an example of what you would expect to get. If you cannot provide an example, perhaps you need to do some thinking about your goal here, because your question is not at all well posed.
