I have a numeric 2D array called A with time in the first column (from zero to 2 minutes every 0.01 seconds). I want to find the rows that match times = 10 : 10 : 100;
When I type find(10==A(:,1), I get 1001
When I type find(20==A(:,1), I get 2001
Why when I type find(times==A(:,1) does it give these values: [1001, 12957, 24913, 36869, ...]?
These values of times (which are 10, 20, 30, ...) are at rows [1001, 2001, 3001, 4001, ...], so that's what I expected.
I know I don't really need a find() in most situations because I can use indexing, but that doesn't work either:
gives error msg: The logical indices in position 1 contain a true value outside of the array bounds.
because A(:,1)==times gives value of 12957 for the second index which is outside of array A bounds.
