How can I catch all warnings during a Simulink simulation?

I want to catch all warnings issued during the simulation of a Matlab/Simulink model. The result of simulation should be an array of warnings, as there might be more than one warning. The ideal code would look something like this (except that catch…

How can a Simulink model discover it's own filename and path?

I would like to display some information about a Simulink model, without first knowing the filename. The information will be displayed in the model itself. Something similar, mfilename, is available for MATLAB programs. Is there an equivalent for…

Is there an option for a Simulink Scope to display the layout in single column?

I mean like in the picture from below, for example if I'm having more than 4 layouts to have all of them in a single line, not in a matrix. Does anyone know?

set a condition for a switch lower than a certain value

Is it possible to realize the condition <=1 or =1 with any switch of the simulink library?? The idea is to use it for priority. For example the device with the priority 1 should be selected for further signal processing?
