This makes it 8 bits for 8 bit architectures, 16 for 16, etc. The C standard has required the minimum size of an int be 16 bits for many decades.

WebAn image whose data matrix has class uint8 is called an 8-bit image; an image whose data matrix has class uint16 is called a 16-bit image. The image function can display 8- or 16-bit images directly without converting them to double precision. However, image interprets matrix values slightly differently when the image matrix is uint8 or uint16 . Web32 bit: LINT-2 63: 2 63-1: 64 bit: ULINT: 0: 2 64-1: 64 bit: Hint.
