while loop step is not working in simulink
显示 更早的评论
hello
My simulink diagram is looping 4times
During loop, make some flg signal ( [1,0,0,0] )
And run subsystemblock, it is not make 4 signal just 2signal.
how can i make 4 signal in below diagram ?
1. loop 4times
2. make flg signal in 4times while loop ( [ 1,0,0,0] )
3. subsystem run useing by flg signal
4. now result - only make 2signals.

Switch / Action ports do not create new signals each time a new sample is processed through them. Any one branch is turned on or off, but remains that way until it is changed. So you have one signal transition when flg is 1, and another when flg first becomes 0 -- but then it stays that way with the 0s that follow.
Think of it as being like an on/off switch. The switch is turned on with the first 1, and then it stays on until the time of the first 0, at which point it is turned off. And it then stays off. The switch is not effectively reversed on at each candidate time: if the input value does not change, there is no transition.
