imadjust() might be the function you're looking for. Try it.

You can use imadjust() in the Image Processing Toolbox. It's not interactive though. Or simply multiply your image by a factor between 0 and 1.

MATLAB: Adjust brightness and contrast

You are probably looking for the imadjust command. As you can see in the documentation the basic syntax for imadjust is

OutputImage = imadjust(InputImage,[low_in; high_in],[low_out; high_out])

where low_in,high_in,low_out and high_out are between 0 and 1. Hence you could assign predetermined values to those and run imadjust on your images. There also a gamma parameter which you can add in you call to imadjust. This factor is used to enhance in a non-linear fashion low or high intensity signals. More info here

If you have the Image Processing Toolbox take a look at the Image Viewer App

Hope that helps get you started!
