<div dir="ltr"><div><div><div><div>I have been spending enjoyable time with gsll's (and gsl's) histogram routines.<br><br></div>A small bug in the code popped up. In histogram/histogram.lisp the grid:copy method calls histo-copy and histo-clone. The arguments in those calls are incorrect. This is what the method should look like:<br>
<br><div style="margin-left:40px">(defmethod grid:copy ((source histogram) &key destination &allow-other-keys)<br> (if destination<br> (histo-copy source destination)<br> (histo-clone source)))<br></div>
<br></div>In the original, source and destination were swapped.<br></div><br></div>The same fix applies to the method that specializes on histogram2d.<br><br>Mirko<br></div>
