if true
% q=[q(2*qk)(2*qk)(4*qk)]
end
I am getting the following error
()-indexing must appear last in an index expression.
in the editor its showing Cannot call or access into a temporary array.
how to correct the error

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.

q=[q(2*qk),(2*qk),(4*qk)]

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?

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. If you want to post your code, check out this link: http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers

Invalid expression. When calling a function or indexing a
variable, use parentheses. Otherwise, check for mismatched
delimiters.
