To calculate the gradient of an image in MATLAB, you can use the gradient
function. The gradient
function calculates the directional derivative of an image, which is the rate of change of pixel values in the x and y directions.
Here's an example of how to use the gradient
function:

In this example, we first read in an image and convert it to grayscale. We then use the gradient
function to calculate the directional derivatives in the x and y directions. Finally, we compute the magnitude of the gradient using the x and y derivatives, and display the original image and the gradient magnitude.
