How do I display a MATLAB error from a Simulink Model?

Hi... I construct a model in simulink... How i make to appear in Matlab window one message with error?

For exemple, when V<0.1 appear in Matlab window: "Voltage error!"

Hi,

it exists a block called MATLAB Function. Simply take this block and take the voltage as input signal. In this Block you can use normal MATLAB syntax and you could write

%warning is displayed
warning('warn text')
%or error is displayed
error('error text')

Can I show error message without stopping the simulation?

You could also use the the blocks in the Model Verification library, such as Check Static Lower Bound. Set the lower bound to 0.1 and set the callback to something like:

disp('Voltage error!')

You can uncheck the Stop simulation option if you want the simulation to continue even after this condition has been detected.

I don't know Simulink, but I think it can run MATLAB commands such as

uiwait(warndlg('Voltage Error: Voltage < 0.1!'));
