Hi, everyone,
I have a string of numbers and want to apply an if command on all the numbers in the text, for example if a number is equal to or less than 2 within this text, and if it is, I want the function to display and identify this number by how far down in the string of numbers it is.
eg out of these numbers I want the command to then output 4, 6 and 7
12
35
46
1
4
1.3
0

Try this:
v = [12
35
46
1
4
1.3
0];
loc = find(v <= 2)
producing:
loc =
4
6
7
.
