The path line of the k-wave library has to precede all the other toolboxes:</p> <p>&gt;&gt;oldpath=path;<br /> &gt;&gt;path('C:\Users....\k-Wave',oldpath)</p> <p>Possibly this is preventing some confusion between original Matlab functions and k-wave's functions.</p> <p>D </p> http://www.k-wave.org/forum/topic/error-in-kspacefirstorder2d#post-8307 Mon, 13 Sep 2021 07:58:28 +0000 dvirzonis 8307@http://www.k-wave.org/forum/ <p>Hello.<br /> Just installed the k-wave (latest version) on Matlab R2016a and trying to run a "Homogeneous Propagation Medium Example".<br /> It produces the following error message:</p> <p>Error using .*<br /> Matrix dimensions must agree.</p> <p>Error in kspaceFirstOrder2D (line 920)<br /> ux_sgx = dt .* rho0_sgx_inv .* real(ifft2( bsxfun(@times, ddx_k_shift_pos, kappa .*<br /> fft2(p)) )) / 2;</p> <p>Error in example_ivp_binary_sensor_mask (line 69)<br /> sensor_data = kspaceFirstOrder2D(kgrid, medium, source, sensor);</p> <p>Error in run (line 96)<br /> evalin('caller', [script ';']);</p> <p>Any suggestions or advice?<br /> Regards<br /> Darius </p>
