When using if statements, I am trying to find a set of data that fits the condition I have given. How can I find where the data with the right conditions is located?

Ran in:
You can use logical indexing.
Example:
A = rand(10,1) ; % data for demo
idx = A > 0.3 & A < 0.8 ;
idx
idx = 10×1 logical array
0 1 0 1 0 0 0 0 0 0
find(idx)
ans = 2×1
2 4
A(idx)
ans = 2×1
0.7124 0.7594

What are the row and column sizes are the two data sets? Do they have common times (or any other specific identifying row information)?
