I obtain grayscale image' 'img' that I add to a 'stack' i.e. image array by:
So If I have say 5 images in the imgArray, I have been saving them to disk by writing them out individually as tifs via:
for k=1:5
BUT, I want the option to say the array of images as a single file i.e. an image stack. I thought the following would do it
h = errordlg('Error Saving Image STK')
But it always fails. Is there an obvious error?

According to the matlab documentation you can store multiple images to a single file as follows:
See --> Write Multiple Images to TIFF File.

Correction. It should be possible to save the tiffs using any extension using fmt option
imwrite(___,fmt) writes the image in the format specified by fmt, regardless of the file extension in filename. You can specify fmt after the input arguments in any of the previous syntaxes.

I have seen 'WriteMode' 'append' suggested everywhere, but for some reason MatLab still saves the files as seperate tiffs rather than a single file, why would this be?

Hey there! Even I'm trying to use to convert a .avi file to a .tif STACk but unfortunately the code just converts it to a set of .tif images despite using 'WriteMode' and "append".
Here's the code, it's similar to that of Joe.
%% To convert avi files to tif images
obj = VideoReader('video.avi');
vid = read(obj);
frames = obj.NumberOfFrames;
% This just converts them to a set of images
% for x = 1 : frames
% imwrite(vid(:,:,:,x),strcat('frame-',num2str(x),'.tif'));
% end
%This is meant to amend that and to make a .tif stack
for x = 1 : frames
imwrite(vid(:,:,:,x),strcat('frame-',num2str(x),'.tif'), 'Compression', 'none','WriteMode', "append");
