- Yair Altman (1 day 19 hours ago): @Priyanka – this functionality is only available in Matlab’s new graphics system (HG2), which became officially available in Matlab release R2014b (i.e., 3 releases...
- Yair Altman (1 day 19 hours ago): @Shahbaz – I believe that your Matlab installation is corrupt. Try to uninstall Matlab and then re-install it from scratch.

- Ilya (1 day 22 hours ago): If I’ve understood (and tested) it correctly, Inf-padding at the end of any of the 2 input vectors should not be a problem (sometimes vectors are 0 or NaN padded to preserve...
- Priyanka (1 day 22 hours ago): Thanks for this useful tip! I’m still finding my way around MATLAB, and unfortunately I’m stuck – was wondering if I can access the hidden MarkerHandle in Matlab...
- Yair Altman (2 days 16 hours ago): @Flo – R2011b uses JVM 1.6 by default – you’re trying to run it with a version that is 2 full generations newer, so I’m not surprised that some things...
- flo (2 days 18 hours ago): I tried out Matlab 2011b and JVM 1.8 The GUI ist starting and plots are shown well. If I set the figure visible off, an then set the figure visible on, there are just the axes elements,...

- Sandor Toth (5 days 21 hours ago): Dear Yair, do you know a way to change the XTickLabel vertical position, a.k.a its distance from the x-axis line? The generally suggested solution is to recreate the labels...
- Yair Altman (6 days 14 hours ago): @Christina – sounds like something’s funky with your Java. Java warnings cannot be suppressed. You have a very old Matlab release so try upgrading to a newer release.
- Christina (9 days 17 hours ago): In Matlab2007 I’m trying to use the JSlider but I keep getting a “Warning: Transform Fcn…” error every time the GUI repaints. I cannot find a way to get...
- Ed Yu (9 days 18 hours ago): Yair, I would say with regard to loading classes through the java (root) classloader directly should not be that risky… As long as MATLAB is using Java, the root classloader...

Plot legend title
Titles to plot legends are easy to achieve in HG1 (R2014a or earlier), but much more difficult in HG2 (R2014b or newer).
Using Infiniband with Matlab Parallel Computing Toolbox
Infiniband networking can significantly improve PCT performance in Matlab parallelization and distributed computing.
Transparent legend
Matlab chart legends are opaque be default but can be made semi- or fully transparent.
Customizing Matlab uipanels
Matlab uipanel controls can be customized using Java in ways that are impossible with plain Matlab.
