However, you could use the 3D C++ code with one of the dimension sizes set to 1. If you try and use the C++ code via MATLAB (i.e., using <code>kspaceFirstOrder3DC</code>), the code will complain about the various matrices not being in 3D. However, if you follow the <a href="http://www.k-wave.org/documentation/example_cpp_io_in_parts.php">Saving Input Files In Parts Example</a>, it should work (perhaps with minor changes to some sub-functions).</p> <p>We haven't benchmarked the code in this case, but I imagine it will still be faster than the MATLAB code. Let me know if you try this and get stuck on something.</p> <p>If it's warranted by the performance, I will have a look into creating a <code>kspaceFirstOrder2DC</code> function to automate this for the next release.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/can-i-use-the-c-version-to-simulate-2d-cases#post-5240 Tue, 15 Sep 2015 19:05:29 +0000 weiyanglin 5240@http://www.k-wave.org/forum/ <p>I am doing grid convergence study, but k-wave did not give converged solution for some cases yet. With the last grid k-wave took 2 weeks to finish. I will definitely need an optimized C++ version. </p>
