How do I remove element lower/greater than a certain value in a matrix?

Lets say I have

A = 1
    3
    2
    7
    4
    10
    12
    9
    8
    15
    13

So in this case, i want to remove values lower than 5 and greater than 11 , so i will end up getting this:

A = 7
    10
    9
    8

How should I do this?

Try this:

A = [1
    3
    2
    7
    4
    10
    12
    9
    8
    15
    13]
rowsToDelete = A < 5 | A > 11
A(rowsToDelete) = []

Give you exactly what you asked for.

Use my helper function iswithin

>> A(iswithin(A,5,11))
ans =
   7
  10
   9
   8
>> >> type iswithin

function flg=iswithin(x,lo,hi)
% returns T for values within range of input
% SYNTAX:
%  [log] = iswithin(x,lo,hi)
%      returns T for x between lo and hi values, inclusive

flg= (x>=lo) & (x<=hi);
