Try casting it to single or double precision after loading:</p> <p><code>source.p0 = single(source.p0);</code></p> <p>Brad. </p> http://www.k-wave.org/forum/topic/error-when-using-own-dcm-file#post-7877 Thu, 08 Oct 2020 17:25:05 +0000 milksoup 7877@http://www.k-wave.org/forum/ <p>Hi,</p> <p>I'm using the load external image example to try and load my own CT slice. </p> <p>I changed loadImage to dicomread and Nx;Ny = 512 instead of 128 to match my image.</p> <p>I got this error and I don't know how to fix it:</p> <pre><code>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);</code></pre> <p>Thank you in advance </p>
