Count Numbers between two values in random vectors

I am trying to find the how many numbers are between two specific values in a random vector. For example, How many are betweens 1 and 5

A=[1,2,3,4,5]

is should return 3 in this case. So what is the function that allow me to identify this?

Hi,

use logical indexing and count the result:

X = rand(1, 1000);
nBetween05and09 = sum(X>0.5 & X<0.9)

find(A==5)-find(A==1)-1

I have a random vector, so t did not work in my case. In other words, e.g X=rand(1,1000) and I want to find how many between 0.5 and 0.9. Would it be the same method you provided? can you help me.

Thanks
