The waitKey function in the matplotlib library is used to pause execution of a program until a key press event occurs.
It is typically used in conjunction with the imshow function to display images and wait for user input before continuing.

Here is an example of how you can use waitKey in a Python program:

Copy code
import cv2
import matplotlib.pyplot as plt

# Load an image
img = cv2.imread('image.jpg')

# Display the image using matplotlib
plt.imshow(img)

# Wait for the user to press a key
plt.waitKey(0)

# Close the window
plt.close()
In this example, the imshow function is used to display the image, and the waitKey function is used to pause execution until the user presses a key.
The waitKey function takes an integer argument that specifies the maximum time to wait in milliseconds. If the argument is set to 0, the function will wait indefinitely until a key is pressed.

I hope this helps! Let me know if you have any other questions or need further assistance.
