Hi Alessandro,
I understand that you would like to efficiently calculate the binary vector ‘q’ based on the vector ‘t_ref’ and two constant values ‘t1’ and ‘t2’. The value of ‘q’ should be 1 when ‘t_ref’ is greater than or equal to ‘t2’ or less than or equal to ‘t1’, and 0 otherwise. Instead of using a line search, you can directly calculate the binary vector ‘q’ using logical operations without iterating through each element of ‘t_ref’. Here's an efficient approach:
q = (t_ref <= t1)| (t_ref >= t2);
In this approach, the logical operator ‘<=’ compares each element of ‘t_ref’ with ‘t1’, resulting in a logical vector of the same size as ‘t_ref’ with 1 where the condition is true and 0 otherwise. Similarly, the logical operator ‘>=’ compares each element of ‘t_ref’ with ‘t2’. Finally, the logical OR operator ‘|’ combines the two conditions elementwise, resulting in the desired binary vector ‘q’ .
This approach avoids the need for a line search or iterating through each element of ‘t_ref’, making it more efficient.
Note that ‘t1’ and ‘t2’ should be scalar values, not vectors, as per your description. If you have multiple values of ‘t1’ and ‘t2’, you can use element-wise comparisons and logical operations to calculate ‘q’ for each pair of ‘t1’ and ‘t2’ values.
Hope this answers your question.
