Matlab: Raw image DNG BitsPerSample 10 not support - matlab

Question

As Steve Eddin posted in http://blogs.mathworks.com/steve/2011/03/08/tips-for-reading-a-camera-raw-file-into-matlab/, I followed and copied the following code, running in MATLAB 2014b. As a result, I got the following error."Reading images with a BitsPerSample of 10 is not supported". I checked info and info.SubIFDs{1}, I got the following results in INFOS. I have searched on google for the problem, but there is no enough information. Therefore, I posted this problem here and hope someone gives me solutions.
CODE::
warning off MATLAB:tifflib:TIFFReadDirectory:libraryWarning
t = Tiff('Non-Invasive DNGs/WP_20150311_15_03_14_Raw__highres.dng','r');
offsets = getTag(t,'SubIFD');
setSubDirectory(t,offsets(1));
cfa = read(t);
close(t);
ERROR::
Error using Tiff.constructBlankOutputImage (line 2448)
Reading images with a BitsPerSample of 10 is not supported.
Error in Tiff/readAllStrips (line 2046)
imageData = obj.constructBlankOutputImage(imageSize,bps,sampleFormat);
