Hello Guys
I have this below error. Does anyone know how to fix this error?
Arrays have incompatible sizes for this operation.
Error in kspaceFirstOrder2D (line 920)
ux_sgx = dt .* rho0_sgx_inv .* real(ifft2( bsxfun(@times, ddx_k_shift_pos, kappa .* fft2(p)) )) / 2;
Error in Prac01 (line 41)
recorded_data = kspaceFirstOrder2D(kgrid,medium,source,sensor);
Are you running an initial value problem with smoothing turned on, and have the curve fitting toolbox? There can sometimes be a clash between the smooth function in k-Wave and the smooth function in this toolbox. If that's the case, try removing the curve fitting toolbox from the path when running k-Wave.
I also encountered this error, and my solution was to move the K-wave toolbox higher in the add-on search order. In 2023b, go to the "Home" tab ==> click on "Set Path" (under the "Preferences" tab) ==> select all K-wave-related paths ==> click the "Move to Top" button ==> save ==> close.
Given that I did not want to uninstall the curve fitting toolbox, this seemed like a decent compromise, but I'm not sure how it will affect my use of the curve fitting toolbox. The first example in the cf toolbox's example code for the smooth function seems to work for snow, but given that I have not used that function directly before, perhaps it will cause issues later on.
