Alternatively, you can use cat:

c = cat(1, a, b);

You can also use straight MATLAB matrix building:

c = [a; b];

This is assuming that the images have the same number of columns. Doing c = [a b] concatenates matrices column-wise. If you want to do it by row, use the semi-colon. Take a look at this basic tutorial on MATLAB operations here to get you started: http://www.mathworks.com/help/matlab/examples/basic-matrix-operations.html

Get the images and make a matrix of them, use for matrix a and matrix b, 

c = vertcat(a,b)
