imwrite image as a tif

I proceeded my two satellite images and then I obtain D variable. Then I try to save my D variable as a tif image with the name of imagee in Deltaw folder but it gives these errors.

You are trying to write single precision, which imwrite() does not know how to handle for TIFF files. You will need to use the Tiff class. See http://www.mathworks.com/matlabcentral/answers/7184-how-can-i-write-32-bit-floating-point-tifs-with-nans

Funny that imread() read in his A and B as singles, and computed D (which would also be a single), but that imwrite() does not handle singles like imread() evidently does.

[Walter Roberson]

It happens. The facilities of imread() and imwrite() are not always mirror images.

Thank you Roberson. I use D=double(D) and it seems that it is working now.
