i would like to hide a message dialog, which pops up when I click on a subsystem mask to modify a parameter.
this is the message:
*| Warning
attempt to change parameters of a blocks within a library link.
These changes can later be discarded or propagated to the library
and two buttons OK CANCEL|*
I tried with
[a, MSGID] = lastwarn();
warning('off', MSGID)
warning off
but it is still there jumping around all the time.
do you have any idea of how I can hide this dialog box?

See this snippet of code for an example. It has some instructions in there for you to adapt it to any error.
% Turn off note "Warning: Added specified worksheet." that appears in the command window.
% To set the warning state, you must first know the message identifier for the one warning you want to enable.
% Query the last warning to acquire the identifier. For example:
% warnStruct = warning('query', 'last');
% msgid_integerCat = warnStruct.identifier
% Command window will show this:
% msgid_integerCat =
% MATLAB:xlswrite:AddSheet
% You need to pass the expression with the colons in it into the warning() function.
% Turn off note "Warning: Added specified worksheet." that appears in the command window.
warning('off', 'MATLAB:xlswrite:AddSheet');

Thank you for the help, I tried these instructions:
msgid_integerCat = warnStruct.identifier
warnStruct = warning('query', 'last')
but I cannot get the identifier of the message box
While it appears I can only fish out that one
identifier: 'Simulink:SL_UsingDiscreteSolver'
state: 'off'

Well first of all, you'd have to reverse the order of those two lines:
warnStruct = warning('query', 'last')
msgid_integerCat = warnStruct.identifier
To turn that off warning, you'd do:
warning('off', 'Simulink:SL_UsingDiscreteSolver');
but from your comment, it looks like that one is already off so I think you got the wrong warning code.
