When you say a byte array, is it a rgb uint8 3D matrix? or a 1D array of hexidecimal digits? If so, you will need to know the image size and whether the image is color or just gray scale.

reconstructed_image = reshape(typecast(int8(arrayfun(@byteValue, YourByteArray)),'uint8'), [4000, 3000, 3]);
There might well be better ways: this is the way I could get to work.

I try this but still error
I try to input YourByteArray with '[B@5faeada1' and didn't change for @byteValue
Error:
Error using arrayfun Unrecognized function or variable byteValue
What is byteValue? And what is YourByteArray?
