Graphics

Other 8-Bit and 16-Bit Array Support

MATLAB supports several other operations on uint8 and uint16 arrays, including:

• Reshaping, reordering, and concatenating arrays using the functions reshape, cat, permute, and the [] and ' operators
• Saving and loading uint8 and uint16 arrays in MAT-files using save and load. (Remember that if you are loading or saving a graphics file format image, you must use the commands imread and imwrite, instead.)
• Locating the indices of nonzero elements in uint8 and uint16 arrays using find. However, the returned array is always of class double.
• Relational operators
