MATLAB: Get the msgid of a certain warning

errorsimulink

When I generate c-code from my Simulink model, 19000+ warnings were generated as ~20 categories. One of category is ' An ERT or ERT derived target is required to preserve the names of alias data types in the generated code. Reverting to builtin types during code generation.' . I want to ignore this type of warning by using the [warning('off', msgid)] command. However, because these warnings lie in the middle of all warnings, I cannot get their msgid by using ' _ lastwarn_' function. Is there anyway to get msgid just based on the warning texts?

Thanks a lot!

Hi Guanyu Wang:

use the function warning with enabled verbosity to display extended warning messages (including suppression command):

 warning('on','verbose')

The command has to be written before executing your code containing warnings. Shutting it off again is done straight forward by

 warning('off','verbose')

In MATLAB 7.0 (R14), the warning display is set to "off" by default. However, you can change this option by using the following command:

warning verbose

Likewise, you can choose the option to be "on" or "off" explicitly with the following lines of code:

warning verbose on
warning verbose off

To set the warning display to "on" by default, you can put the above command in your startup.m file.

MATLAB: How to turn off a particular warning in MATLAB

This change has been incorporated into the documentation in Release 2010a (R2010a). For previous releases, read below for any additional information:

The general method for suppressing a warning message is to issue the following command at the prompt:

warning('off', MSGID)

The string 'MSGID' is a unique identifier that corresponds to a particular warning message.

There are two ways to determine what a warning's identifier is, so that it can be suppressed later:

1) Just after the specific warning has been issued, run the following command:

[a, MSGID] = lastwarn();

This will save the message identifier to the variable MSGID. Then you can use the command given above to turn that particular warning off.

2) Turn on verbose warning messages with the following command:

warning on verbose

When warnings are displayed, they will include the command that can be used to turn that warning off.
