Hi all,
I am trying to find lowest number excluding zero and inf from a vector:
I wanna the output to be:
r= 0.5
index= 6
I tried the following but it does not give me what I want:
clearvars
clc;
x = [1 3 2;-1 inf 0.5];
[r,index] = find (min(x(:)>0));

Try this:
x = [1 3 2;-1 inf 0.5];
[r,index] = min(x(x>0))
producing:
r =
0.5
index =
5
The find call is not necessary here.
