Search a larger dataset through a smaller data set of intervals

I have a time dataset A = 29000x1 and two time datasets Start = 100x1 End = 100x1. I want to run A through the interval I have created with Start and End to end up with a dataset that falls between. I have tried isbetween, I have tried to set a min and max, I have tried a withinrange, but no matter what I do I still get an error that it cannot run because they need to all be the same size. Is there anyway to run a set of data through a time interval that isn't the same size?

It's not at all clear what you mean by "run a set of data through a time interval".

Can you post a small(ish) illustration of just what it is you're trying to do? Give us a sample dataset and then a corollary time set that illustrate what you have; then show us what you want/expect for output.

An example would be data in table A : [8:10:05 8:55:26 8:12:02] Start = [8:10:00 8:11:00 8:40:00] End = [8:10:25 8:12:20 8:45:00] . I was trying to run table A through Start and End intervals so it would return [8:10:05 8:12:02] met the time intervals provided. each row of A needs to go through each time interval Start <= A >= End .

Taking a wild stab at what might be intended from the above data arrangement; assuming that the larger timetable(?) covers a time span from at least Start(1) through End(end) and that the Start/End arrays define a set of subsets of the total that are wanted to be selected and that these would be disjoint sections. Like, for example, maybe the Start array is the Monday 8AM and End is the corresponding next Friday 5PM??? If it is something like the above, depending upon just what it is that defines the start,stop times, there may be more efficient ways to write the logic, but not having any info on that, we'll just go with what we can guess might be the Q?

B=[];
for i=1:numel(Start)
  B=[B;A(isbetween(A,Start(i),End(i)))];
end

The above uses dynamic reallocation because there's insufficient info to know how to preallocate the output array...

Yes, you have the correct concept, except it would be like Start time Monday at 8am and End time would be Monday at 8:45am. I added that line to my code and it at least didn't throw the "matices of same size error", so thank you for that. But it isn't pulling the records that fall within that Start and End window. So now I am thinking that I will reverse the way I am looking and take the Start = 100x1 End = 100x1 table and combine them into one table C=100x2. Then try to run table C through the larger table A = 29000x1 and pull out what records fall within?

 A : [8:10:05 8:55:26 8:12:02] 

That A is not a legal MATLAB variable representation; you need to convert A and the two lookup tables to datetime or timeofday values; otherwise you're doing character comparison and there's no concept of before, after, between in string data other than a lexical sort.

"I added that line to my code..."

One line may not be sufficient depending upon what the other code is; not to mention the above about what the data actually are.

WE NEED TO SEE THE ACTUAL CODE TO QUIT HAVING TO GUESS! The thing is, "we can't debug what we can't see/touch..." and we can't see your terminal from here nor read your mind. "Help us help you!"
