for k = 1:length(tifFiles)

rgbImage = imread(filename);
% operations on "I"
[rows columns numberOfColorBands] = size(rgbImage);
subplot(2, 2, 1);
imshow(rgbImage, []);
pause;
% Extract the individual color planes.
redPlane = rgbImage(:, :, 1);
greenPlane = rgbImage(:, :, 2);
bluePlane = rgbImage(:, :, 3);
figure, imshow(redPlane);
figure,imshow(greenPlane);
figure,imshow(bluePlane);
b = redPlane + greenPlane + bluePlane;
figure,imshow(b);

Line 20 in the code you've shown is
figure,imshow(greenPlane);
Can't see any problem there. "index exceeds matrix dimensions" means you've used an index larger than an array dimension, e.g.,
>> x=rand(1,5); x(6)
Index exceeds matrix dimensions.
DBSTOP will stop the code execution at the point where the error occurs. You can then check the size of the array being indexed and the value of the index and see what is wrong.
