Nevertheless, I am a bit confused, why don't you use the Version 1.2.1? </p> <p>Ps: Are you sure that you want to simulate a 3000x3000x10000 matrix?</p> <p>Best </p> http://www.k-wave.org/forum/topic/compatibility-of-current-k-wave-version-with-matlab-r2017b#post-6870 Tue, 04 Jun 2019 13:55:52 +0000 daniel3141 6870@http://www.k-wave.org/forum/ <p>Hello together,<br /> I really enjoy using this toolbox for my master sc. - project (photoakustic imaging via annular ordered transducerelements). Until now, I have been working with the toolbox for simuations in 2D - things seem to work, but when I try to generate 3D kgrid I get errors. That´s my code:</p> <p>clear all;<br /> c0=1500; %[m/s]<br /> f_mean=5.5e6; %[Hz]<br /> f_max=10e6;%[Hz]<br /> x_size=0.15; y_size=x_size;<br /> z_size=0.05; %transducerelement z-dimension: 20mm</p> <p>%Compute d_ and N_ based on domain size and f_max<br /> c0_min=c0; %c0_min: smallest speed of sound in the medium<br /> points_per_wavelength=3;<br /> dx=c0_min/(points_per_wavelength*f_max); dy=dx; dz=dx;<br /> Nx=round(x_size/dx);<br /> Ny=round(y_size/dy);<br /> Nz=round(z_size/dz);<br /> %Create grid<br /> kgrid=makeGrid(Nx,dx,Ny,dy,Nz,dz);</p> <p>When I use "makeGrid", I get:</p> <p>Error using makeGrid (line 41)<br /> User defined classes are not supported in this version of MATLAB. Please use a more recent version of MATLAB, or k-Wave V1.1.</p> <p>When I use "kWaveGrid" instead, I get:<br /> Error in kWaveGrid (line 424)<br /> kgrid.k = zeros(kgrid.Nx, kgrid.Ny, kgrid.Nz);</p> <p>I am a little bit confused - the Matlab version i use (R2017b) should be up to date enough!<br /> Does anybody is familiar with this problem? I am hesitating to move to an older version of k-wave, since I really want to use the fast and gpu - optimized code of the newer versions!</p> <p>Kind Regards!<br /> Daniel </p>
