Can someone tell me why can't I get this to work?! It should be working!
The script is as below;
function export_Img_2_Header( img, filename )
%EXPORT_IMG_2_HEADER Summary of this function goes here
% Detailed explanation goes here
sizeArray = numel(img);
fileID = fopen(filename,'w');
fprintf(fileID,'//Image on header\n');
fprintf(fileID,'unsigned char img[%d] = {',sizeArray);
img_sq = reshape(img,[1 sizeArray]);
for idx = 1:numel(img_sq)
val = img_sq(idx);
if idx ~= sizeArray
fprintf(fileID,'%d ,',val);
else
fprintf(fileID,'%d',val);
end
end
fprintf(fileID,'};\n');
fclose(fileID);
end

Please mention, what "can't get it to work" means. The code looks fine, so I guess you made a mistake at calling it.

In this file exchange - https://www.mathworks.com/matlabcentral/fileexchange/72535-image-to-c-c-array-converter, I have written a script to generate a C/C++ array which can be saved as a header file for use with various embedded displays.
Hope that helps.

Maybe this helps - smarter without a loop:
function export_Img_2_Header( img, filename )
% EXPORT_IMG_2_HEADER Create C++ header file containing image data
[fileID, msg] = fopen(filename, 'W');
if fileID == -1
error('Cannot open file for writing: %s, %s', filename, msg);
end
% Maybe:
img = im2uint8(img);
n = numel(img);
fprintf(fileID, '// Image on header\nunsigned char img[%d] = {', n);
fprintf(fileID,'%d ,', img(1:n-1));
fprintf(fileID,'%d};\n', img(n));
fclose(fileID);
end
