Read floating point multi-channel TIFFs in Matlab >=R2009b

For reading a TIFF image in Matlab usually the imread function suffices:

d1 = imread('myfile.tif'); 

This call will even load single channel f32 (32bit floating point) images. But for multi-channel f32 images will fail. This is not a surprise, since most of the applications don't even load the single channel f32 files.

Starting from version R2009b Matlab includes a new Tiff class that implements much more of the TIFF format, allowing to read and write many flavors of TIFF files. The call is slightly different from imread: 

t = Tiff('myfile.tif'); 
d2 = t.read();
