Conversion of Error and Warning Message Identifiers

For R2011b, error and warning message identifiers have changed in Aerospace Toolbox.

Compatibility Considerations

If you have scripts or functions that use message identifiers that changed, you must update the code to use the new identifiers. Typically, message identifiers are used to turn off specific warning messages.

For example, the Aero:FlightGearAnimation:NeedTimeData identifier has changed to aero:FlightGearAnimation:NeedTimeData. If your code checks for Aero:FlightGearAnimation:NeedTimeData, you must update it to check for aero:FlightGearAnimation:NeedTimeData instead.

To determine the identifier for a warning, run the following command just after you see the warning:

[MSG,MSGID] = lastwarn;

This command saves the message identifier to the variable MSGID.

Note   Warning messages indicate a potential issue with your code. While you can turn off a warning, a suggested alternative is to change your code so it runs warning-free.

Demos

The following demos are new:

• Visualizing World Magnetic Model Contours for 2010 Epoch — Visualize contour plots of the calculated values for the Earth's magnetic field using World Magnetic Model 2010 (WMM-2010) overlaid on maps of the Earth.

• Visualizing Geoid Height for Earth Geopotential Model 1996 — Calculate the Earth's Geoid height using the EGM96 Geopotential Model.

Function and Function Element Being Removed

The following table lists the function and function element name being removed for R2011b.

Function or Function Element Name	What Happens When You Use the Function or Element?	Use These Functions or Function Elements Instead	Compatibility Considerations
wrldmagm'2000' or '2005' epoch year	Warns	For model years between 2000 and the start of 2010, use igrf11magm. For model years between 2010 and the start of 2015, use wrldmagm.	For model years between 2000 and the start of 2010, use igrf11magm. For model years between 2010 and the start of 2015, use wrldmagm.
