URL: <http://savannah.gnu.org/bugs/?35033> Summary: mangled filled contour plot Project: GNU Octave Submitted by: bpabbott Submitted on: Sun 11 Dec 2011 01:43:39 PM EST Category: Plotting Severity: 3 - Normal Priority: 5 - Normal Item Group: Incorrect Result Status: None Assigned to: None Originator Name: Ben Abbott Originator Email: Open/Closed: Open Discussion Lock: Any Release: dev Operating System: Any _______________________________________________________ Details: This bug was found by Walter White <address@hidden> on posted to help-octave Octave <address@hidden>. Walter found that Octave mangles the *filled* contour for his complicated example. I verified that Octave and Matlab produce similar equivalent results for contour(), so only the *filled* version is impacted. I've attached he m-file (walter.m) which may be used to produce the plot. Results for Matlab R2011b and Octave (tip: de90542b7afc) have been attached. My impression is that the problem is with __contour__.m _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Sun 11 Dec 2011 01:43:39 PM EST Name: walter.m Size: 617B By: bpabbott <http://savannah.gnu.org/bugs/download.php?file_id=24562> ------------------------------------------------------- Date: Sun 11 Dec 2011 01:43:39 PM EST Name: my_FEM_matrix.txt Size: 807kB By: bpabbott <http://savannah.gnu.org/bugs/download.php?file_id=24563> ------------------------------------------------------- Date: Sun 11 Dec 2011 01:43:39 PM EST Name: Walter-Octave.png Size: 302kB By: bpabbott <http://savannah.gnu.org/bugs/download.php?file_id=24564> ------------------------------------------------------- Date: Sun 11 Dec 2011 01:43:39 PM EST Name: Walter-MATLAB.png Size: 61kB By: bpabbott <http://savannah.gnu.org/bugs/download.php?file_id=24565> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?35033> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
