Image processing with an exponential function

I need to run the exponential function on an image. Could someone help with the code to perform this operation? exp('image.jpg') doesn't work. Also if you have any other functions I could try on my images.

I want to see the effects of using this type of function on my image. Once I apply the exponential function then I will run the image thru the heat equation. I want to smooth my image but I need something more than the heat equation. So I am looking at different function(exponential, trigonometric and others) and looking at what happens to the images.

I have no idea what you want to do. Do you want (for some reason) "e" raised to the power of the gray level of the image???? If so, for what purpose?

MyImage = imread('image.jpg');
exp(MyImage)

This doesn't work.

exp(double(MyImage))
