Or maybe when you say write you mean imwrite to write the image array out to disk:
imwrite(yourImage, filename);
Using precise unambiguous terminology is important if you want a precise answer.

Why do you wanna write an image into an array. Use reshape if you really want.

get() the CData property of the image; that will be an array.

Simply do this
targetImg = imread("path");
targetImg = targetImg(:); % You can take a transpose too if you like
If you need to convert it to one of the primitive types, you can do so by
targetImg = double(targetImg);
targetImg = float(targetImg);
% etc.
If you have performance/speed/parallel processing related issues. I suggest you also look into get() CDATA property of the image. I am not sure why you need the array of an image. I must say that I cannot remember if about the float(). But the point is proven. Hope this helps you.
