If statement display problem

Hello, I am checking if all values of a vector Fr are within a certain range as shown:

% code as follows:
for i = 1:1:length(loop)
if Fr(i) > 0.1 && Fr(i) < 0.3
  disp('0.10 < Fr < 0.30. Criteria met.')
else
  disp(' Fr outside interval. Criteria not met.')
end
end

Here Fr is a vector with length(loop) values. I want the code to show the message only once if all the elements of Fr are within the range. If not, the message for Fr outside the interval should also only be shown once.

In other words, when running the code I want only one message to be displayed. Either all values are within the interval or they are not.

Is there a way of doing this?

Use the all function:

Fr = 0.0001*rand(1,10)+0.2;                         % Create ‘Fr’

if all((Fr > 0.1) & (Fr < 0.3))
  disp('0.10 < Fr < 0.30. Criteria met.')
else
  disp(' Fr outside interval. Criteria not met.')
end

Change some of the elements of ‘Fr’ her to test it. Your code works with this small tweak.

 No loop. 

if all(Fr>0.1 & Fr<0.3)
