How do I find the maximum value of a number that is less than a value. For example, max(19,23) gives a max of 23, but how do I find the max if its under 21. So in this case, I want it to give me 19.
I am wanting to find the largest element of possibilities which is greater than or equal to 17, and less than or equal to 21.

a=[ 23, 19, 12,18,30,17,20,28,21,65,22,31];
b=a(a>=17 & a<=21) % elements between greater equal 17 and smaller equal 21
b = 1×5
19 18 17 20 21
maximumelement=max(b) % maximum element
maximumelement = 21

v = 1:20
v = 1×20
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
max_treshold = 15;
b_max = max(v(v < 15))
b_max = 14
This is pretty easy in Matlab.
