For uint8 images,
negativeImage = uint8(255) - YourImage;
For average intensity, rgb2gray() and then mean2()
You need to explain what contrast value you are looking for. One possibility is at https://www.mathworks.com/matlabcentral/answers/81133-how-to-calculate-contrast-per-pixel-cpp-of-an-image#answer_90845

Try imadjust() to change the image, or colormap() to change just how it's displayed.
