Display multiple causes of an error settings

Hello all,

What settings (and where) should I do for displaying the multiple causes of an error.

For example if I build a model and I miss some parameters (that I used in the model) in workspace how is possible to receive an error showing me all this parameters (at the same time) that I miss?

At the moment I receive an error for one parameter, then I save it, then I try to build the model again and I get another error with the next parameter that I forgot to save in workspace, and so on... I do not what this to happen.. it would be perfect to display the multiple causes of the error.

Thanks! Bye!

Which Matlab/Simulink version you are using ?

I'm using the 2011b version.

I am also using same version and I can see all the missing parameters at one time. And I don't think that there is any special setting for that. See may error dialog:

You can try in another way also.

In command window enter command

>> get_param('YourModel','ReferencedWSVars')

This returns all the model parameters which are from workspace. And for missing parameters it give error listing all the missing parameters.

Hey,

While compiling the model I want to display all the errors (in one) via command line.

What do you mean by display all the errors (in one) ?

Isn't above function get_param('YourModel','ReferencedWSVars') do the same job.

I mean to see all the parameters that are missing in one error. See below an example (this is what I an trying to get in my command window):

 Caused by:
Error using X (line 11)
Error due to multiple causes.

    Error using X (line 11)
    Error evaluating parameter 'Value' in 'Model/Constant'
        Error using X (line 11)
        Undefined function or variable 'Parameter1'.
    Error using X (line 11)
    Error evaluating parameter 'Value' in 'Model/Constant1'
        Error using X (line 11)
        Undefined function or variable 'Parameter2'.
    Error using X (line 11)
    Error evaluating parameter 'Value' in 'Model/Constant2'
        Error using X (line 11)
        Undefined function or variable 'Parameter3'.
    Error using X (line 11)
    Error evaluating parameter 'Value' in 'Model/Constant3'
        Error using X (line 11)
        Undefined function or variable 'Parameter4'.

From this single error I know that I have to load in workspace the 4 parameters: Parameter1, Parameter2, Parameter3 and Parameter4.

At the moment I receive first an error containing only the part related to Parameter1. I save this parameter in workspace, I compile again the model and I receive another error about only Parameter2 that I am missing, I save it I compile again and after that again I get an error about only Parameter3 and so on...

[TAB]

This is what i got using command

>> get_param('YourModel','ReferencedWSVars')

Use this command before you start the model compilation/simulation. I don't think you have even tried this.

Hey, First thank you for trying to help me.

I tried this command when you wrote me first above, but still I get the error only about the first parameter... I was thinking that it's about a Matlab setting about how to display an error..

[TAB]

I don't know what could be the reason. But you can go through command Simulink.findVars. It is used to trace the variables/parameters used in model. I have never used this in practice.

Below are the other links which explains its usage:
