imadd:

Z = imadd(X,Y) adds each element in array X to the corresponding      

    element in array Y and returns the sum in the corresponding element

    of the output array Z.  X and Y are real, nonsparse, numeric arrays

    or logical arrays with the same size and class, or Y is a scalar

    double.  Z has the same size and class as X unless X is logical, in

    which case Z is double.

    Example 1

    Add two images together:

        I = imread('rice.png');

        J = imread('cameraman.tif');

        K = imadd(I,J);

        figure, imshow(K)

    Example 2

    Add a constant to an im
