We'll incorporate this into the code with some error checking in the next release / update. We also plan to submit a bug report about interp3 to Mathworks.</p> <p>Unfortunately there is no private messaging system, but your explanation/code above is clear, and will be easy enough for others to follow.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/kspaceplanerecon-in-matlab-r1202b#post-1062 Fri, 23 Nov 2012 04:01:40 +0000 luke.burgess 1062@http://www.k-wave.org/forum/ <p>Hi,</p> <p>I have become very familiar with kspacePlaneRecon and kspaceLineRecon over the last year using matlab r2010a.</p> <p>I have just recently changed to matlab r2012b, and installed k-wave v1.0. I saw the note that the mentioned reconstructions no longer work.</p> <p>I believe I have fixed the issue for the kspacePlaneRecon, by interchanging interp3 with griddedInterpolant. I believe the other change is the removal of the asterisk, located prior to the interpolation method. e.g, replace '*nearest' with 'nearest'. This feature used to speed up the interp functions but has since been removed. </p> <p>I have solved the problem for kspacePlaneRecon, I have the results from the matlab comparison of the original and my version of both kspacePlaneRecon and the Example_pr_3d_fft_planar_sensor. Is there a way to post these html files?</p> <p>Here is a list of the changes I made to kspacePlaneRecon.</p> <p>Line 106<br /> replace with<br /> interp_method = 'nearest'; </p> <p>Line 186<br /> Replace with<br /> F = griddedInterpolant( w,kgrid.ky, kgrid.kz, p, interp_method);<br /> p=F(w_new,kgrid.ky, kgrid.kz);</p> <p>Changes to example_pr_3D_FFT_planar_sensor.m<br /> Line 95<br /> F = griddedInterpolant(kgrid_recon.x - min(kgrid_recon.x(:)),kgrid_recon.y - min(kgrid_recon.y(:)), kgrid_recon.z - min(kgrid_recon.z(:)), p_xyz, 'nearest');<br /> p_xyz_rs = F(kgrid_interp.x - min(kgrid_interp.x(:)), kgrid_interp.y - min(kgrid_interp.y(:)), kgrid_interp.z - min(kgrid_interp.z(:)));</p> <p>I will shortly apply the equivalent to kspaceLineRecon and post it.</p> <p>Is there a private message system for this forum, so I can organise to email my m files or comparison htmls. I can just post my email if there is not. </p>
