To write an image to a folder using the imwrite function in Matlab, you can follow these steps:

1. Load the image using the imread function. For example:

img = imread('image.jpg');

Specify the file path and name for the output image. For example:

output_path = 'C:\myfolder\output_image.jpg';

1. Note that you need to replace C:\myfolder with the actual path to your folder and output_image.jpg with the desired name for the output image.

2. Use the imwrite function to write the image to the specified folder. For example:

imwrite(img, output_path);

1. This will write the img variable to the file path specified in output_path.

Here's the complete code:

% Load the image
img = imread('image.jpg');

% Specify the output file path and name
output_path = 'C:\myfolder\output_image.jpg';

% Write the image to the specified folder
imwrite(img, output_path);

Make sure to replace the file paths and names with your own values.
