If you re-download v1.4 (and make sure that other versions aren’t on the path), that should fix the issue. </p> http://www.k-wave.org/forum/topic/issues-with-kspacefirstorder3d#post-8848 Wed, 28 Jun 2023 23:08:14 +0000 rothstein 8848@http://www.k-wave.org/forum/ <p>Hi! I'm an undergraduate student relatively new to k-wave and keep running into a persistent issue. I'm using the most up to date version of the toolbox, and am trying to simulate ultrasound passing through a CT of a human skull, but every time I encounter the kspaceFirstOrder3D code, I get the same error. </p> <p>Error using nargout<br /> You can only call nargin/nargout from within a MATLAB function.</p> <p>Error in kspaceFirstOrder_inputchecking (line 33)<br /> if nargout == 2 &amp;&amp; ~strcmp(calling_func(3).name, 'benchmark')</p> <p>Error in kspaceFirstOrder3D (line 495)<br /> kspaceFirstOrder_inputChecking;</p> <p>I am truly stumped on this, as I've doubled checked everything, including old forum posts, and cannot figure this out. Any help would be much appreciated!! </p>
