In the Simulink External Mode Control Panel, there is a Arm/Cancel Trigger button. I would like to execute this from the command line.
The mex commands are as follows, but I do not know how to perform them action: EXT_ARM_TRIGGER and action: EXT_CANCEL_LOGGING
What I really want to do is change the sampling duration in External Signal and Triggering dialog, but I am unable to do so unless the trigger is unarmed.
Any advice would be much appreciated, Thank you

short answer is to use this function to arm trigger:
set_param(gcs,'ExtModeCommand','armWired')
and this one for cancel trigger:
set_param(gcs,'ExtModeCommand','cancelWired')
all parameters come in last part of link above
