After re-installing it seems as everything is fine. Not sure why it was throwing an error in the curve fitting toolbox, however. </p> http://www.k-wave.org/forum/topic/homogenousheterogenous-propagation-medium-examples#post-163 Mon, 06 Jun 2011 23:26:49 +0000 Bradley Treeby 163@http://www.k-wave.org/forum/ <p>This sounds like an error thrown by the <code>smooth</code> function which is part of the curve fitting toolbox (not the <code>smooth</code> in k-Wave; unfortunately the functions have the same name although we may change this in a future release). Do you also have this toolbox installed?</p> <p>This suggests the k-Wave toolbox may not be correctly installed, although MATLAB obviously found the simulation functions OK so that is puzzling. What happens if you type <code>help smooth</code> at the commmand line? Can you see the k-Wave entry under the contents in the MATLAB help browser?</p> <p>We have tested k-Wave on most MATLAB versions since 7.5 so it shouldn't be a version issue. </p> http://www.k-wave.org/forum/topic/homogenousheterogenous-propagation-medium-examples#post-162 Mon, 06 Jun 2011 18:51:57 +0000 spencerj 162@http://www.k-wave.org/forum/ <p>I installed the k-wave toolbox using MATLAB 7.10.0 and without changing anything attempted running both of these example scripts. Both of them threw the same error in the "smooth" curve-fitting function used by kspaceFirstOrder2D function that stated:</p> <p>??? Error using ==&gt; smooth at 131<br /> X and Y must be the same length.</p> <p>Error in ==&gt; kspaceFirstOrder2D at 428<br /> source.p0 = smooth(kgrid,source.p0,true);</p> <p>Reading through the help guide it doesn't look like anything needs to be adjusted for these scripts to run properly. Am I missing something or is this a bug due to MATLAB version compatibility? Thanks. </p>
