There are two ways you can concatenate image and text in MATLAB:
  1. Convert the text to numeric form, such as by using double(), and pad it out so that it has the same number of columns as the image you are concatenating it on to.
  2. Put the image and text as different entries in a cell array
Based upon your code, though, I think the real answer for you is rather different: You should be converting the text into a series of bits and embedding it into an image using techniques such as LSB embedding.
