This option runs the simulation on an Nvidia GPU using the third party toolbox <a href="http://www.accelereyes.com">Accelereyes Jacket</a>. You must have this toolbox installed before you can use this option. </p> http://www.k-wave.org/forum/topic/error-using-example_us_bmode_linear_transducerm#post-1462 Sat, 16 Mar 2013 06:19:05 +0000 Marcoags 1462@http://www.k-wave.org/forum/ <p>Dear All.</p> <p>When I use the example_us_bmode_linear_transducer.m m-file to run a simulation it´s report the following error:</p> <p>Undefined function 'gzeros' for input arguments of type 'double'.</p> <p>Error in kspaceFirstOrder3D/@(sz)gzeros(sz,'single')</p> <p>Error in kspaceFirstOrder_createStorageVariables (line 208)<br /> sensor_data_buffer = castZeros([num_sensor_points, sensor_data_buffer_size]);</p> <p>Error in kspaceFirstOrder3D (line 708)<br /> kspaceFirstOrder_createStorageVariables;</p> <p>Error in example_us_bmode_linear_transducer (line 238)<br /> sensor_data = kspaceFirstOrder3D(kgrid, medium, transducer, transducer, input_args{:});</p> <p>Anyone knows what is happening? Did I forgot some library ou function? What function is gzeros?</p> <p>Thank´s Marco. </p>
