I'm afraid that even after reading both your posts several times, I have NO IDEA what you are getting at. You talk about milliseconds (thousandths of a second), then say you want to divide 3 s into intervals of 0.5 s (i.e. 500 milliseconds). And how you get this: > new one= [ 3:0.05:7,10:0.05:13,16:0.05:19] from 3 10 16 is a complete mystery to me.
To get help, you need to explain things better.
