Multiplying column with scalar

How can I multiply 2 sets of data with a scalar to get 3rd set of data. I got two sets of data. I don't know how to format them into a matrix or a vector that is the 1st problem. The 2nd problem is multiplying that with a scalar. Data is this : x= 1,2,3,4,5,6, . y = 7, 7, 7, 8, 9, 10.
And I need to multiply that with some scalar let's say 4. So I type in make matrix x = [1 2 3 4 5 6] and y= [7 ;7; 7; 8; 9; 10] And type this x*y*4 and get a 6x6 matrix. I want to get a 1x6 or 6x1 matrix with results. What would be optimal solution?

x = [1 2 3 4 5 6]
y= [7 ;7; 7; 8; 9; 10]
z=x.*y'*4

you can use ./ and .* and .^ to make element by element operation,
c=a.*b, where a and b have the same size, in your case, x and y should be both row vector or column vector, that's why I used y'
