Write a GUI based Matlab program to open a true-color image, display the image, then show the red, green and blue channel of the image in three other axes. Your GUI should look the same as the example below.
I have written the GUI and am able to upload the original image and display it in the GUI, however I need help with adding the 3 other images with the 3 channels. I tried using imsplit in my callback function, but it is not working. Any help is appreciated!

RGB images in Matlab are stored as 3D arrays. As the third dimension stores the colors, something like this should work (pay attention to a conversion to double (and a rescale) that many be needed)
imshow(IM(:,:,1)), title('red')
