multiply_imaginary_integer

Engine.multiply_imaginary_integer(x, y)
Returns the ciphertext resulting from the multiplication of a ciphertext and a complex number whose real part is 0 and imaginary part is an integer. Does not consume any level.
  • Input:
    • x: int | Ciphertext
    • y: int | Ciphertext
    • x and y must be passed as positional arguments.
    • One of the inputs must be a ciphertext. The other input is an integer value of the imaginary part.
  • Output:
    • Ciphertext

Warning

  • The matrix form does not yet support this operation.
