I have a size(x) function that gives answer: 1 23 (x is a vector with 23 points). I can take the second value like this

k=size(x) 
k(2)

Is there a more immediate way to do this? in a single command, something like.. size(x)(2) ?

The simplest method is:

k = size(x, 2)

The second argument of the "size" method is the dimension in which to query - in your case the 2nd dimension

Sometimes you can use length() or numel().
