Screenshot from 2021-10-13 15-47-12.png

Here is the screenshot. What is the problem here? Yesterday I was able to access the Data field in the Command Window with the code line in the screenshot.

Is it a common problem, or there is a problem in my script?

Thank you.

在 MATLAB Online 中打开

Start with experimenting:

img2 = reshape(img, [4, 376, 672]);
rgb  = permute(img2([3 2 1], :, :), [2, 3, 1]);
figure, image(rgb);

This is called "gunshot programming" and an anti-pattern. But if it works...
