   Hello.
   Just installed the k-wave (latest version) on Matlab R2016a and trying to run a "Homogeneous Propagation Medium Example".
   It produces the following error message:

   Error using .*
   Matrix dimensions must agree.

   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 example_ivp_binary_sensor_mask (line 69)
   sensor_data = kspaceFirstOrder2D(kgrid, medium, source, sensor);

   Error in run (line 96)
   evalin('caller', [script ';']);

   Any suggestions or advice?
   Regards
   Darius

   Solved the issue by changing the Matlab path setup. The path line of the k-wave library has to precede all the other toolboxes:

   >>oldpath=path;
   >>path('C:\Users....\k-Wave',oldpath)

   Possibly this is preventing some confusion between original Matlab functions and k-wave's functions.
