How to open or read an image with float 32 format type?

I want to open my image with 32 float format in Matlab. But by using imread() it gives me white image. Originally my image is a gray scale image.

Thanks in advance.

imshow(I,[])

Use [] to force imshow to show the full range rather than the default range of [0 1] where everything greater than 1 will be saturated to white.
