Logical lookup between two dates
显示 更早的评论
I am trying to create a logical lookup between 3 date vectors. Vector a is the lookup value (a date), Vector b is a start date, c is an end date. a is a larger size than b and c, which are both the same size.
I want to return a logical response (1) when a is b<=>c.
The vector size seems to be the main problem when trying to write this. I know there is a simple way to do it, but cant find the answer.

Can you share a sample of your code? Also since you mentioned that a is larger than b and c, so how do you want to deal with that?

What does "b<=>c" mean? What exactly is a "date vector"? Please provide some input data.

Assuming R2016b or later:
sum(a >= b' & a <= c')
In earlier versions
sum(bsxfun(@ge, a, b') & bsxfun(@le, a, c'))
a, b, c must be date numbers
