save image to file in matlab

To save an image to file in Matlab, you can use the imwrite function. Here is an example code snippet:

main.m
% Read image from file
img = imread('my_image.png');

% Save image to file
imwrite(img, 'my_saved_image.png');
111 chars
6 lines

In this example, we first read an image from file using the imread function. We then save the image to file using the imwrite function, specifying the image array as the first input and the desired file name as the second input. You can save the image in various file formats, such as PNG, JPEG, TIFF, etc., by changing the file extension in the file name.
