Thread Subject: nurbs toolbox with 2008b

Hi all,

Upon upgrading to MATLAB 2008b, I have found that under certain conditions MATLAB will hang (requiring the process killed from the task manager) when invoking the nrbplot command of the nurbs toolbox (http://www.mathworks.com/matlabcentral/fileexchange/14247).

Firstly, there is no error when I try to plot a simple surface such as listed in the nrbplot help file:
>> nrbplot(nrbtestsrf, [20 30])

But when I try to plot some of my own surfaces, MATLAB hangs. It is quite possible that my nurbs surface definitions aren't standard, and are contributing to the problem. However, my surfaces plotted without problem in MATLAB 2007b. I am using the same "addpath" command to include the nurbs toolbox in both installations.

A likely source of the problem is that I have both the nurbs toolbox and the iges2matlab toolbox (http://www.mathworks.com/matlabcentral/fileexchange/13253). These both contain a file bspeval.dll.

When I call the iges2matlab function, I receive the following warning:
Warning: In the directory "S:\matlab\_includes\file_exchange\cad_readers\nurbsR2006b", bspeval.mexw32 now shadows
bspeval.dll
 Please see the MATLAB 7.1 Release Notes.

Is there a difference in how 2007b and 2008b handle the case where there is a conflict in files on the matlab path? I can't seem to find it in the release notes.

Thanks,
Sven.
