Error while using 3d plot in Matlab 2019b

[Hesam Sharghi]

Whenever I try to use the 3d plot in matcont GUI, I get the following error.

Index exceeds the number of array elements (4).

Error in GUIPlotConf/syncRegionWithAxes (line 226)
                     obj.configs{3}.region = newregion(5:6);

Error in GUIPlotConf/fitAxis (line 393)
             obj.syncRegionWithAxes();

Error in GUIPlotConf>@(o,e)plotconf.fitAxis() (line 447)
            uimenu(mhandle , 'Label' , 'Fit Range' , 'Callback' , @(o,e)
            plotconf.fitAxis());

Error while evaluating Menu Callback.

I used Matlab 2019b version. I reinsatll matcont, but it did not help.

Dear Hesam,

The cause is Matlab not opening a real 3Dplot, but a figure with only two axis. This means that when you would change the plot ranges, then the z-axis limits are not defined (therefore the newregion(5:6) is the problem). Once you rotate the figure, this third axis is really there. So we need to add it.

For now, a solution to avoid problems with the initial projection in a 3D graphic window of Matcont under MATLAB R2019b, is to add the command

                view(45,45);

after line 123
obj.activatePlot(plotconf, true);
in the file /matcont7p1/GUI/GUIOutputManager.m of your installation of MatCont.

Best regards, Hil Meijer

Dear hilmeijer,

Thank you for your clearifications.

Hello Hesam,

I am facing the same problem. Have you solved it somehow?

[Hesam Sharghi]

Hi,

I tried Matlab 2018 b, and everything seems fine.

[Dionysios Moutevelis]

Thank you very much for your immediate response.
