tf.complex(real, imag, name=None)

See the guide: Math > Complex Number Functions

Converts two real numbers to a complex number.

Given a tensor real representing the real part of a complex number, and a tensor imag representing the imaginary part of a complex number, this operation returns complex numbers elementwise of the form \(a + bj\), where a represents the real part and b represents the imag part.

The input tensors real and imag must have the same shape.

For example:

# tensor 'real' is [2.25, 3.25]
# tensor `imag` is [4.75, 5.75]
tf.complex(real, imag) ==> [[2.25 + 4.75j], [3.25 + 5.75j]]


  • real: A Tensor. Must be one of the following types: float32, float64.
  • imag: A Tensor. Must have the same type as real.
  • name: A name for the operation (optional).


A Tensor of type complex64 or complex128.
