MATLAB: How to make .bin file

image binary file

I have image file (bmp), and i need to change it to format *.bin file.
Please help me if you know about it.
I tried below code but it seems the binary file is not good:
> a=imread("untitled.bmp")
>fid = fopen('binfile.bin', 'w+')
>fwrite (fid,a,'uint8')
>fclose(fid)
Thank you and Best Regards.

"I tried below code but it seems the binary file is not good". How do you define "good"?
Following code shows the image is saved and loaded properly.
img = imread('pears.png');
fid = fopen('test.bin', 'w+');
fwrite(fid, img, 'uint8');
fclose(fid);
fid = fopen('test.bin', 'r');
img_loaded = uint8(fread(fid, inf, 'uint8'));
fclose(fid);
img_loaded = reshape(img_loaded, size(img));
imshow(img_loaded);
