Conj#

This example shows how to use the pylops.basicoperators.Conj operator. This operator returns the complex conjugate in both forward and adjoint modes (it is self adjoint).

import matplotlib.pyplot as plt
import numpy as np

import pylops

plt.close("all")

Let’s define a Conj operator to get the complex conjugate of the input.

M = 5
x = np.arange(M) + 1j * np.arange(M)[::-1]
Rop = pylops.basicoperators.Conj(M, dtype="complex128")

y = Rop * x
xadj = Rop.H * y

_, axs = plt.subplots(1, 3, figsize=(10, 4))
axs[0].plot(np.real(x), lw=2, label="Real")
axs[0].plot(np.imag(x), lw=2, label="Imag")
axs[0].legend()
axs[0].set_title("Input")
axs[1].plot(np.real(y), lw=2, label="Real")
axs[1].plot(np.imag(y), lw=2, label="Imag")
axs[1].legend()
axs[1].set_title("Forward of Input")
axs[2].plot(np.real(xadj), lw=2, label="Real")
axs[2].plot(np.imag(xadj), lw=2, label="Imag")
axs[2].legend()
axs[2].set_title("Adjoint of Forward")
plt.tight_layout()
Input, Forward of Input, Adjoint of Forward
