   Hi,

   I'm using the load external image example to try and load my own CT slice.

   I changed loadImage to dicomread and Nx;Ny = 512 instead of 128 to match my image.

   I got this error and I don't know how to fix it:

   Error using  .*
   Integers can only be combined with integers of the same class, or scalar doubles.
   
   Error in smooth (line 134)
       mat_sm = ( max(abs(mat(:))) ./ max(abs(mat_sm(:))) ) .* mat_sm;
   
   Error in kspaceFirstOrder_inputChecking (line 1540)
           source.p0 = smooth(source.p0, true);
   
   Error in kspaceFirstOrder2D (line 537)
   kspaceFirstOrder_inputChecking;
   
   Error in example_ivp_loading_external_image (line 61)
   sensor_data = kspaceFirstOrder2D(kgrid, medium, source, sensor);

   Thank you in advance

   Hi milksoup,

   Likely your dicom image data has been loaded as int16 (or similar). Try casting it to single or double precision after loading:

   source.p0 = single(source.p0);

   Brad.
