Create a vector from components of old vectors

I have a 3x5 matrix, I want to be able to take the 1st row and the 3rd column to create a row vector. I know how to seperately extract a row and a column, but how would I go about using that in order to create a new vector without typing individual elements?

How do you want to combine the 1st row and 3rd column in your row vector?

I am supposed to create a row vector. Meaning I should take the first row, then make the numbers from the third row follow, in a row like fashion.

i.e row 1: [1,2,3,4,5]

Column 3

1

2

3

new vector [1,2,3,4,5,1,2,3]

For a matrix A such as

A = rand(3,5);

this should work:

v = [A(1,:) A(:,3)']
