how to multiply a 1xn matrix with a 1xn matrix and get the answer in the form of a 1xn matrix

a have the following matrices:

a= [1 5 3 8]

and

b= [4 6 1 9]

how do i multiply each term in a by the equivalent term of the other matrix in b?

so the answer would be:

ab= [4 30 3 72]

I'm really stuck, I've been transposing them but it obviously just gives me one numerical answer..

help!

ab = a .* b; % Note the dot asterisk, dot meaning element-wise

Thanks so much! My mind must have forgotten the dot product today..
