  1. Please format your code, such that we can read it without pain.
  2. I suggest to avoid the brute clearing header "clc; clear all; close all", because this clears the breakpoints of the debugger also. But the debugger would be your friend for finding the reasons for errors.
  3. Please do not interpret the error message, but post a complete copy. While the forum is powerful at solving problems, it is weak for guessing what and where the error is.
  4. img= imag(:,:,:); is meanigless.
  5. The meaning of "dec2d = [... cA1, cH1; ... cV1, cD1 ... ]; " is mysterious.

And even beyond those issues, I don't even know where he's trying to upload the image to . Some website? Here in Answers? If you want to upload it here, use the image icon or the paper clip icon, or both. What line of code is the line that's supposed to do the uploading?
