How to convert byte array to image in matlab?

i have been convert an image to byte array in java and i have

byte array = [B@5faeada1

now i want to convert that byte array to image in matlab, how to do it??

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.

it is rgb uint8 3D matrix, the image size is 4000x3000 and it's a color scale.. how to convert into an image again ??

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?
