How to get output of [110,40] from input of FindAbnormal([65, 95, 110, 80, 40]) using relational and logical operators?

The problem is: The resting heart rate for an average adult between 60 - 100 beats per minute, inclusive. Assign row array heartExtracted with all values in row array heartReadings that do not fall within the normal range.

My code right now is:

function heartExtracted = FindAbnormal(heartReadings)
% heartReadings: Array of hourly heart rate readings
  % Create a logical indexing array to identify readings that are not 60-100
  abnormalReadings = heartReadings((heartReadings < 60) & (heartReadings > 100));
  % Assign heartExtracted all values in heartReadings that do not fall 
  % within the normal range 
  heartExtracted = heartReadings(abnormalReadings);
end

but it's giving me an empty matrix when I run it. Can someone explain why it's giving me an empty matrix, and how to properly write it?

Use logical or | instead of logical and &

a number that satisfies a two conditions <60 and >100 doesn't exist! But you can find numbers that are <60 or >100

I feel so dumb. Thanks for pointing that out, it works now!
