thrust::complex

template<typename T> struct complex

complex is the Thrust equivalent to std::complex. It is functionally identical to it, but can also be used in device code which std::complex currently cannot.

Template Parameters: T – The type used to hold the real and imaginary parts. Should be float or double. Others types are not supported.

Public Types

using value_type = T : value_type is the type of complex's real and imaginary parts.
