Matlab Compiler and imshow fail on execution

We have produced several matlab application for research purpose and I'm looking into compiling them for easier deployment. I've read the documentation and aware that not all parts of matlab can be compiled.

Compiler - supported toolboxes

Compiler - unsupported functions

Image Toolbox - unsupported functions

Here is a simple example that compiles but fails on execution:

    function [ ] = TestImshow( )

        % create image (a white square on a black background)
        I = zeros(400, 400, 'uint8');
        I(100:300, 100:300) = intmax('uint8');

        % show image
        imshow(I);
    end

Error: Undefined function 'imshow' for input arguments of type 'uint8'.

The imshow function is not explicit listed as a function that cannot be compiled, and if so the mccExcludedFiles.log should list this function during compilation and it doesn't.

Several other users have posted about this problem, also with official answers by Mathworks on how to include the function missing - see this post.

Adding the extra parameter "-a imshow" to mcc or using the function pragma does not solve the problem

    function [ ] = TestImshow( )
        %# function imshow
        ...

I also encounter the same issue for dicomwrite, and I think something is fundamentally wrong with my setup or how it is supposed to be used. I've tried on different computers and matlab versions without any luck!

Here is another example with dicomwrite

    function [ ] = TestDicom( )

        %#function dicomwrite

        % create image (a white square on a black background)
        I = zeros(400, 400, 'uint16');
        I(100:300, 100:300) = intmax('uint16');

        % create minimum dicom header with default values
        H = struct('PixelSpacing', [1 1], ...
                    'ImagePositionPatient', [0 0 0], ...
                    'ImageOrientationPatient', [1 0 0 0 1 0], ...
                    'ImageType', 'ORIGINAL\\PRIMARY', ...
                    'RescaleIntercept', -1024, ...
                    'RescaleSlope', 1);

        dicomwrite(I, 'test.dcm', 'ObjectType', 'CT Image Storage', 'CreateMode', 'Create');
    end

Error: Undefined function 'dicomwrite' for input arguments of type 'uint16'.

Have any of you succeeded to compile and execute one of these simple examples, and can you (or Mathworks) provide a guidance or solution to this issue with missing functions?
