doc command.
Currently the Help Desk should be used with Netscape Navigator Release 3.0 or Microsoft Internet Explorer 3.0 (the Help Desk does not work as well with earlier releases of those products).
When invoked from Microsoft Internet Explorer, the index search facility generates HTML output that takes the place of the Help Desk page in the browser's page hierarchy. Consequently, the Back button or hyperlinks to the Help Desk will not work as expected. To return to the Help Desk from the index search page, use the Refresh button. Also, the search may not work correctly when invoked the first time over a slow network; subsequent searches will work correctly.
Note the JIT compiler must be disabled to run the index search applet under Internet Explorer. To turn off JIT, click the View menu and then click Options. Select the Advanced tab, and then deselect the checkbox labeled Enable Java JIT Compiler.
On the 68K Macintosh, the index search facility requires Netscape 3.0. In addition, the index search facility is extremely slow on the 68K doc to access this document online.

Platform-Specific Issues
Before you can print from a Microsoft or Novell NetWare network environment under Windows 95 or NT, you must map the LPT1 port to the printer you want to use. To map LPT1 on Microsoft networks, issue this command at the system's command prompt:net use LPT1: \\server\printerwhere
server is the name of the server sharing the printer and printer is the name of the printer.
On Novell NetWare networks, use this command:
capture l=1 q=printerwhere
printer is the name of the print queue.
If you are using a Microsoft network, you can map LPT1, or you can edit the printopt function to change the definition of pcmd to:
COPY /B %s \\server\printer:where
server is the name of the server sharing the printer and printer is the name of the printer.

Printing with Ghostscript Drivers
Theprint command does not currently work using Ghostscript drivers on the HP700, DEC Alpha, and IBM RS6000 platforms.
API Characteristics That May Change in Future Releases
This section lists some specific characteristics of the MATLAB 5 API (Application Program Interface) that are likely to change in future releases.mexAtExit routines. This was not true of MATLAB 4. You can override this behavior by calling the new MEX API routine, mexLock(). This allows you to lock the MEX-file in memory. MEX-files that are locked should be on the MATLAB path. If, after changing directories, a locked MEX-file is no longer on the MATLAB path, it will not be unloaded but can no longer be executed.
mexIsLocked currently always returns the value 1.
Notes for MATLAB 5 Beta Users
Read this section only if you have worked with Alpha or Beta versions of MATLAB 5, and are now working with the FCS (First Customer Ship) version of MATLAB 5. This section describes features and characteristics of MATLAB 5 that were introduced during the MATLAB 5 Alpha/Beta program that have changed either during the MATLAB 5 Alpha/Beta program or in the MATLAB 5 FCS version. The material presented in this Late-Breaking News describes some aspects of the MATLAB 5 language not currently mentioned elsewhere in the documentation. The MATLAB 5 features are discussed in the MATLAB 5 New Features Guide. If you have previously used MATLAB 4, you will be particularly interested in the section "Upgrading to Version 5.0."argname Function Changed to inputname
Theargname function has been renamed to the inputname function.
bittest Function Renamed bitget
Thebittest function has been renamed bitget.
The function bug, which during the MATLAB Alpha/Beta program enabled you to create a bug report, has been removed for FCS. Use the Help Desk, as described in the section "Help Desk", above.
The function extract, which extracted cell array contents, has been removed. Use direct cell array indexing with the { } notation to access the contents of an array.
fields.m File Renamed fieldnames.m
The M-filefields.m has been renamed fieldnames.m.
The numeric function has been removed. Use double to convert a character into its numeric codes.
rightjust Function Renamed to strjust
The functionrightjust, which right-justifies a character array, has been renamed strjust.
structs Function Combined into struct
The functionstructs, which creates structures, has been combined into struct.
The Axes Stretch property has been removed. MATLAB now disables the stretch-to-fill behavior whenever the Axes DataAspectRatioMode, PlotBoxAspectRatioMode, or CamerViewAngleMode is set to manual. Note that specifying a value for the DataAspectRatio, PlotBoxAspectRatio, or CamerViewAngle sets the associated mode to manual.
Axes ViewPortScale and ViewPortScaleMode Properties Removed
The functionality that was embodied in theViewPortScale property is now achievable using the CameraViewAngle property. Note that setting ViewPortScale to 1 is equivalent to using the new zoom fill option.
ChangeFcn and CurrentProperty Properties Removed
TheChangeFcn and CurrentProperty properties have been removed.
bar and barh Functions Changed
Thebar and barh functions no longer support the two output argument forms that they did during the MATLAB 5 Alpha/Beta program:
[xb,yb] = bar [xb,yb] = barh
colordef Function Replaces Several Functions
Thecolordef function replaces the kdefault, wdefault, default4, and cleardef functions.
ExecutionQueue Property Removed
TheExecutionQueue property has been removed. The BusyAction property provides similar functionality.
See the axes function in the online MATLAB Graphics Reference for more information about each property.
HandleVisibility Property Replaces HiddenHandle Property
The HandleVisibility property replaces the HiddenHandle property.
HiddenVisibility is a property of all objects. It controls the scope of handle visibility within three different ranges. Property values can be:
on -- The object's handle is available to any function executed on the MATLAB command line or from an M-file. This is the default setting.
callback -- The object's handle is hidden from all functions executing on the command line, even if it is on the top of the screen stacking order. However, during callback routine execution (MATLAB statements or functions that execute in response to user action), the handle is visible to all functions, such as gca, gcf, gco, findobj, and newplot. This setting enables callback routines to take advantage of MATLAB's handle access functions, while ensuring that users typing at the command line do not inadvertently disturb a protected object.
off -- The object's handle is hidden from all functions executing on the command line and in callback routines. This setting is useful when you want to protect objects from possibly damaging user commands.
For example, if a GUI accepts user input in the form of text strings, which are then evaluated (using the eval function) from within the callback routine, a string such as 'close all' could destroy the GUI. To protect against this situation, you can temporarily set HandleVisibility to off:
user_input = get(editbox_handle,'String'); set(gui_handles,'HandleVisibility','off') eval(user_input) set(gui_handles,'HandleVisibility','commandline')
-psdefcset Option for print Function Renamed -adobecset
The-psdefcset option to the print command has been renamed to -adobecset. This option specifies that MATLAB should use Adobe's default character set encoding for PostScript, rather than ISO Latin-1 character set encoding.
The ZBuffer Figure property has been removed. Statements that instruct you to set the ZBuffer property should be replaced with statements that set the Figure Renderer property. For example, replace:
set(gcf,'ZBuffer','on')with
set(gcf,'Renderer','zbuffer')
Application Program Interface Feature Changes
mexSearchMATLABPath Function Removed
The functionmexSearchMATLABPath has been removed from the MEX interface. Replace mexSearchMATLABPath() with a call to the MATLAB which function using mexCallMATLAB().
mxCreatDoubleMatrixFromData Function Removed
The functionmxCreateDoubleMatrixFromData has been removed from the MEX interface. Replace mxCreateDoubleMatrixFromData with a call to mxCreateDoubleMatrix, followed by copying the data into the array.
mxReshape and mxGetSize MEX-functions Renamed
The following MEX functions that were introduced in the MATLAB 5 Alpha/Beta program have been renamed:mxReshape is now mxSetDimensions.
mxGetSize is now mxGetDimensions.
mxIsGlobal is now called mexIsGlobal. Rewrite and recompile MEX-files that call mxIsGlobal.
pathdef.m instead of in matlabrc.m.
