imadjust low_in high_in, why only in the range [0,1] ?

Hello, it looks a bit strange that the function imadjust accepts, other than single/double numeric types, also integer types, but actually one is forced to put low_in and high_in values only in the range [0,1]. It seems one forcedly have to convert its input image to double (so increasing a lot memory usage) to adjust an integer valued image.
Am I wrong?

You have misunderstood. You do not need to change the input image datatype. What you are looking at is the contrast limit specification, and contrast is always a relative factor, from no contrast permitted (0) to comple contrast permitted (1)

J = imadjust( A , [600, 30000]/intmax(class(A)) , [0, 65535]/intmax(class(A)) );
Though you would probably use
J = imadjust(A, [600, 30000]/65535, [0 1]);
