Complex random vector
In probability theory and statistics, a complex random vector is typically a tuple of complex-valued random variables, and generally is a random variable taking values in a vector space over the field of complex numbers. If Z 1 , … , Z n {\displaystyle Z_{1},\ldots ,Z_{n}} are complex-valued random variables, then the n-tuple ( Z 1 , … , Z n ) {\displaystyle \left(Z_{1},\ldots ,Z_{n}\right)} is a complex random vector.
