>> v = ones(1,3)

v =
     1     1     1

>> v = [ 1 1 1 ];

>> w = 2:4;

>> w = [2 3 4];

>> x =  x = [[1];[4];[9]]

x =
     1
     4
     9

>> x = [1 4 9]';

>> v * x

ans =
    14

>> v*3 

ans =
     3     3     3

>> v .* x
??? Error using ==> .*
Matrix dimensions must agree.

>> v .* x'

ans =
     1     4     9

>> y = exp(w) 

y =
    7.3891   20.0855   54.5982

>> z = [v' w' x]

z =
     1     2     1
     1     3     4
     1     4     9

>> w*z

ans =
     9    29    50
