In this instance, it is checking to see if the user's MATLAB version supports the interpolation function <code>TriScatteredInterp</code>.</p> <p>We have only tested the k-Wave functions back to 7.5.0 (R2007b). It appears that your version of MATLAB doesn't support the MATLAB class MException (and perhaps other things). As a work around, try deleting the entire try-catch-end statement and replacing it with lines 683 and 684. Alternatively, you could use a binary sensor mask or set the optional input <code>&#39;CartInterp&#39;</code> to <code>&#39;nearest&#39;</code>.</p> <p>It is possible you may encounter other errors after you have rectified this one as k-Wave has not been developed to officially support your version of MATLAB.</p> <p>Thanks,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/me-variable-called-by-kspacefirstorder2d#post-134 Sat, 02 Apr 2011 15:10:50 +0000 Fabrizio67 134@http://www.k-wave.org/forum/ <p>Hello,</p> <p>I just installed the toolbox on a Matlab 7.0 R.14 version (Win XP). Seems everything fine, but while trying running the examples related to the heterogeneous and homogeneous media, the following error pops up:</p> <p>??? Undefined function or variable 'ME'.</p> <p>Error in ==&gt; kspaceFirstOrder2D at 678<br /> catch ME</p> <p>Error in ==&gt; example_ivp_heterogeneous_medium at 69<br /> sensor_data = kspaceFirstOrder2D(kgrid, medium, source, sensor, 'PlotLayout', true, 'PlotPML', false);</p> <p>Any suggestion welcome.<br /> Thank for your attention </p>
