MATLAB 5.3 available on
The MATLAB mathematical package was upgraded from version 5.0 to 5.2
(Release 10) on HKUSUB/HKUSUA (SUN Solaris) systems in early May 1999.
It was further upgraded to version 5.3 (Release 11) on 31 May 1999.
Both versions, i.e. 5.2 and 5.3 , are Y2K compliant with new enhanced features.
Below are the highlights of MATLAB version 5.2 and 5.3 :
MATLAB 5.2 and 5.3 Highlights:
Support for ActiveX technology (Windows):
ActiveX control containment allows users to embed ActiveX controls in MATLAB
ActiveX Automation client capabilities allow developers to programmatically
control ActiveX automation servers (e.g., Excel)
Significant graphics performance speedups using the new OpenGL renderer
Full support for reading and writing of HDF (Hierarchical Data Format)
files via an interface to the HDF library developed by the NCSA (National
Center for Supercomputing Applications)
Performance improvements to 1-D, 2-D, and multidimensional FFTs
Array editor for viewing and interactive editing of 2-D numeric arrays
M-file programming enhancements:
Persistent data in a function and the ability to avoid accidental clearing
New functions for error and warning handling (try/catch, lastwarn)
Support for selectively allowing public access to individual object fields
User-settable recursion limit
Editor/debugger and browsers on Sun, HP, and SGI IRIX platforms
New GUI development features include:
Sizing of GUIs based on font size, allowing true cross-platform development
Tooltips (bubble help) feature for uicontrol-specific help
New uicontrol types: Toggle buttons and Context menus
Truecolor image display on toggle buttons and push buttons (user-definable
New math functions: two ODE methods and Generalized Singular Value Decomposition
Enhanced support for integer data types reduces storage requirements
New Plot Editor provides interactive modification of figure properties
and plot annotation
Support for new NASA standard HDF-EOS (Hierarchical Data Format-Earth Observing
System) including gateways to grid, point, and swath objects
Support for reading and writing PNG (Portable Network Graphics) images
Suite of visualization functions for volumetric data, including isosurfaces
Differential equation solvers for mass matrices and differential-algebraic
Revamped, browser-based M-file Profiler, including generation of summary
reports in HTML format
MATLAB on HKUSUA/HKUSUB can be started from UNIX workstations by the following
Note: Assume that C shell is the user's default login shell and MATLAB on hkusua will be run.
(1) Login a UNIX workstation (e.g. hkusu15, hkuppc20, ......)
(2) Enable the access control on remote machine (hkusua) by typing
the command e.g.:
(3) Display the nodename (e.g. hkusu15) of your workstation by typing the
(4) Login to hkusua UNIX server using the telnet command e.g.:
Note: Steps (5) - (9) should be done within the hkusua login session.
The command xhost + can be found under the path /usr/bin/X11/ (for IBM machines)
and /usr/openwin/bin/ (for SUN machines).
If you are using a SUN workstation, please issue the above commands in
the Console window.
(5) Direct graphic display to your workstation, say hkusu15, by typing
setenv DISPLAY hkusu15.hku.hk:0.0
(6) Invoke MATLAB by typing
Note: the MATLAB invoking command is placed under /usr/local/bin/.
Then, the MATLAB session will start and the following prompt will be
(7) Invoke the on-line help for MATLAB by typing:
(8) Start a Web browser (i.e. Netscape) to read the MATLAB Helpdesk Information
at the >>
Then the "MATLAB Help Window"
will be displayed on the screen of your workstation.
This "MATLAB Help Window"
can be closed by clicking the "Close" button inside it.
(9) To quit MATLAB, type:
Please report to our Helpdesk at 2859 2480 should
you encounter any problems on using the latest version 5.3, (Release 11)
of MATLAB as soon as possible and the MATLAB 5.2 version will be removed
on August 1, 1999 to free more disk space on the systems.

Then the "Netscape: MATLAB Help Desk"
window will be displayed on the screen of your workstation.
To quit this Web browser (Netscape), select "File" from the menu bar
and click the "Exit" option inside the command list.
