Why do I get the error "Identifier 'D' is not a function or a shared variable. To share 'D' with nested function, initialize it in the current scope"?

I got this matlab toolbox called WAFO (Wave Analysis for Fatigue and Oceanography) and when I try to use one of their function files (see attached file), I get the following error:

"Identifier 'D' is not a function or a shared variable. To share 'D' with nested function, initialize it in the current scope. For more information, see Sharing Variables Between Parent and Nested Functions."

I checked this document but I could not resolve the issue. I would highly appreciate if anyone could use this function file with the inputs stated in the comments in the file and help me solve this problem. (I know it's a fairly long file but the error is to do with only 1 variable).

@Keith Adams Yeah, I basically edited line 141 and wrote this:

[u,D] = computeU();

It used to output only u. In addition to this, I edited a nested function (line 203) with the following line:

function [u,D] = computeU()

Hope this helps. Also if you are using WAFO like me, I cannot guarantee this is what the person who created this toolbox intended to do. But it seems to be working and I get their results (I think).
