Answer:
x = 29:73;
x_even = x(2:2:end);
Explanation:
In order to create a vector in Matlab you can use colon notation:
x = j:k
where <em>j</em> is 29 and <em>k</em> is 73 in your case:
x = 29:73
Then you can extract the even numbers by extracting the numbers with even index (2,4,6,etc.) of your vector:
x_even = x(2:2:end);
In the line of code above, we define <em>x_even</em> as all the elements of x with even index from index 2 till the end index of your vector, and an increment of 2 in the index: 2,4,6,etc.
If you want the odd numbers, just use the odd indices of your vector:
x_odd = x(1:2:end);
where <em>x_odd</em> contains all the elements of <em>x</em> with odd index from index 1 till the end index, and an increment of 2: 1,3,5,etc.
