is how can I calculate how many transitions are inside an array?

Solved!
Go to solution

Let’s assume that we have an array of 582 elements. Some of them are above 4 and some of them are below 1,let’s also say that values who are above 4 are equal to True (1) and the values below 1 are equal to False (0). The question is how can I calculate how many transitions are inside the array from 1 to 0?How many peaks I have? Can please someone suggest a code solution for that?

OpenG toolkit has a function called "Boolean Trigger" that can help you.

 

here's how it works.

The example I gave in my previous post works on an array of boolean, as I understand you have an array of numeric so you'll have to add some threshold value so it works.

What I suggest is that you try to implement it and if it doesn't work exactly as you wish, post it here and we'll help you to fix it.$

 

good luck

If you only care about actual transitions and not the type of them, I'm a fan of the simple XOR.

Quite simple.

EDIT: Hehe, just seen that it is indeed very comparable to crossrulz' approach 😉

EDIT 2: Adding improved example
