Hello every body, How can I get the time for 2D signal when the amplitude of the signal met certain condition(s) in simulink ,where the dimentions are: one is the amplitude and the other is the time
MATLAB: Simulink
duplicate postsimulink

As the error suggests, the RunTimeHandle.OutputPort(1).Data (or the Data property of any port) is read-only, so you cannot set it from the GUI. The only way to set port data is if you are writing an S-function block and computing the output signal.
I think we may be able to suggest a different solution depending on what your application is. If you simply want to override a signal with a constant value, then you may want to consider adding 2 Constant blocks and a Switch block to your model.
--------- Signal to override ------|> | | Switch |---------> to other blocks Constant1 -------|-| >=1 | | | Constant2 ---------|> | ---------Initially, your Switch will have the "Signal to override" selected (Constant1=1). In your GUI callback, set the value of the Constant block using:
set_param('modelname/Constant2', 'Value', '5'); set_param('modelname/Constant1', 'Value', '0'); set_param('modelname', 'SimulationCommand', 'update')The second line makes it so the value of Constant2 is selected as the output of the Switch. The third line forces Simulink to take note of the new parameter values.
Hi,
a simple way is using an enabled subsystem:
- Feed the signal to the inport
- Take the clock block, feed into "Compare to Constant" block, feed into enable port.
- The enabled subsystem is configured per default to "hold" output port signals ...
Hope this helps,
Titus
