   Error using h5readc
   The filename specified was either not found on the MATLAB path or it contains unsupported characters.

   Error in h5read (line 66)
   [data,var_class] = h5readc(Filename,Dataset,start,count,stride);

   Error in kspaceFirstOrder3DC (line 569)
   Nx = h5read(output_filename, '/Nx');

   Error in kspaceFirstOrder2DG (line 76)
   sensor_data = kspaceFirstOrder3DC(varargin{:});

   Error in forward (line 45)
   sensor_data = kspaceFirstOrder2DG(kgrid, medium, source, sensor, input_args{:});

   Error in broad_UST_data_3_ink (line 118)
   sensor_data = forward(object, time, medium, sensor);

   Kindly please help me to rectify this error.

   Hello praveenbalaji,

   I met same problem (pasted belov) as you described above when I used MATLAB R2019a to run some codes related k-Wave toolbox, I want to inqury have you find the solution ? Thanks a lot in advance for your reply !

   Hi Yanfe,

   It looks like you don't have the appropriate permissions to execute the k-Wave binary. Try e.g., chmod 755 kspaceFirstOrder-CUDA.
