   Hi All,

   I just discovered the k-wave toolbox and I must say that I am really impressed by its capabilities.

   I am trying to modify the example 'example_tvsp_3D_simulation' so that it runs on the GPU. For this I am using GPUMat. The input parameters are adjusted as follows:

   
input_args = {'DisplayMask', source.p_mask, 'DataCast', 'GPUsingle',...
'CartInterp', 'nearest','DataRecast',true};


   and this is the only adjustment made.

   Running this example then gives

   Error using .*
   Number of array dimensions must match for binary array operation. (ERROR code 15)

   Error in GPUtype/bsxfun (line 19)
   y = feval(f,a,b);
   Error in kspaceFirstOrder3D (line 822)
   ux_sgx = bsxfun(@times, pml_x_sgx, ...

   Error in example_tvsp_3D_simulation (line 80)
   sensor_data = kspaceFirstOrder3D(kgrid, medium, source, sensor, input_args{:});

   Any help would be appreciated.

   Hi Martijn,

   I just tried running the same example with the modifications you mention, but I'm unable to reproduce the error (it runs correctly). I tried on a system running 64-bit Windows 7, MATLAB 2012a, and CUDA 4.2 with a clean install of k-Wave 1.0 and GPUmat.

   Just to double check - did you copy (and rename) the files in the k-Wave Toolbox/other/GPUmat folder to the GPUmat/@GPUtype folder?

   Are you able to run any other examples (for example in 2D) or use the GPUmat toolbox independently of k-Wave?

   Brad.

   Hi Brad,

   Sorry for coming back to this just now. Indeed, I overlooked this part in the manual. Copying/renaming the mentioned files did the trick.

   Thanks,

   Martijn
