| Jun 12, 2013 at 9:11 | comment | added | fizzics | @MichaelE2 Yes this is exactly what was needed. Its does precisely what I want. I had tried to generate something similar myself but failed miserably. I've +1'ed yourself here and whuber's answer on the related question. As this answered my question I'd happily accepted it but theres nothing to formally accept..... Could you or whuber repost a tailored answer maybe? Thanks | |
| Jun 12, 2013 at 8:46 | comment | added | fizzics | @BoLe I looped around multiple times as my real data does that instead of a single loop. It comes from combining multiple time traces that don't necessarily repeated exactly. I thought the multiple loops would be constructive to the question in that sense. | |

Related: 10640. Use zeroCrossings[Last /@ dt - 0.5] or zeroCrossings[plane @@@ dt], where plane[x, y, z] == 0 is the equation of the plane, to find the points between which the crossing occurs.

| Jun 11, 2013 at 14:51 | comment | added | BoLe | Why do you sample over such a broad interval? -Pi to Pi would suffice. | |
