MATLAB: How to get the index of the first non-zero element in an 1-D array in SIMULINK

Question

Hi, guys

I want to find the index of the first non-zero element in a 1-D array in simulink, just like the way that 'find' command in matlab did.

For example:

x = [0 0 5 0 3 0];
idx = find(x~=0, 1, 'first');

The answer would be:

idx = 3.

So, how to do this in simulink?

Thanks!

Use the Find block.
