That will not give an error because it's commented out. Please post the actual code, and all of the actual error message - all the red text displayed in the command window.

In the text book its given as a space.I tried from the file exchange but not getting output.

per isakson on 23 Apr 2013

One can use either space or comma as delimiter. I prefer comma because is more visible.

Does the code of the text book run after you made the correction?

I gave a comma and that error got corrected but its showing more errors.Any way to make it running or is there any running JPEG 2000 available?

Experiment with replacing

[c,s]=wavefast(x,n,'jpeg9.7');

with

[c,s]=wavefast(x.',n,'jpeg9.7');

There is no C in the code you posted, nor is there a wavework(). Should I ask a fourth time for you to post ALL of your error text that appears in the command window in red (not just part of it like you did)? Nah, I think I'll just give up - besides, I don't have the Wavelet Toolbox anyway.
