Greetings, I'm trying to use signal builder to create a custom signal that is just a string of time and value data points but I cannot figure out the format of the "Custom Signal" It has a "Time Values" and a "Y Values" input. I've tried [0 1 2 3] for time and the [0 1 -5 5] along with a host of other syntax and it keeps getting rejected. Can someone give me an example of how to say at time 0 Y=0, at time 1 Y=1, at time 2 Y= -5, and finally at time 3 Y =5

Thanks

Hello,

Time Values: [0 1 1 2 2 3 3]

Y Values: [0 0 1 1 -5 -5 5]

Hope this helps.

Kind regards, Stefan

Thanks - it's just sloppy that the Matlab help system still doesn't give an example of this essential feature. Also missing is the option to simply repeat a signal inverted (e.g.: positive pulse followed by negative pulse), or to repeat a sequence multiple times.
