change the color of a block based on its output

hello,

I'm wondering if there is any way to change a color of a block as a function of the output value.

I thought to use this command

set_param('Test_Forcage_4_Blocs/FUP4', 'BackgroundColor', '[.1, .3, .5]')

but can we do that without using the simulink block, Matlab fcn?

It is possible using an event listener:

I miss something.........

I understood that I should type this instruction

"

listen=add_exec_event_listener(gcb, 'PostOutputs', @MyFunction)

"

while my simulation is running, but I cannot figure out what it is supposed to write inside the body of Myfunction in order to read the ouput value of the block

"

function CallbackFunction(source,eventData)

...

end

"

I should write this code, don't I?

"

rto = get_param(block,'RuntimeObject')

rto.OutputPort(1).Data

"

ps

I just check your other solution
