how to write a image to an array

Might help

Imagearray=double(imread('image's name (path).Image type e.g. tiff'));

Thanks all

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.

Answer 2

[Harshit]

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

Answer 3

[Walter Roberson]

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

Answer 4

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.
