This will not work. Image files contain values e.g. from 0 to 255 for the red, green and blue channel. I do not know any image file format, which accept negative values and I could not imagine, what the value could have as physical meaning.
Either store the array as array, or scale the data to values from 0.0 to 1.0 or from 0 to 255, or to 65536, and store it as grey scale image. See doc imwrite .
