Error using .* Matrix dimensions must agree. HELP

Hi all, when I run this script

kR = 0:1:12;

phi = 0:pi/4:pi/2;

zeta = pi/2;

pre = cos(kR .* sin(phi) .* cos(zeta));

term1 = (1 - 1i * kR) * (1 - 3 * cos (phi) .* cos (phi));

term2 = kR .* kR .* sin (phi) .* sin (phi);

term = (term1 - term2) .* exp (1i * kR);

result = term .* pre;

y = real(result) ./ kR^3 ;

contourf(kR,phi,y)

-----------------------------

I keep getting the error - Error using .* Matrix dimensions must agree.

Error in Forceed (line 9) pre = cos(kR .* sin(phi) .* cos(zeta));

Is this a syntax problem? I can't seem to get it to work. Any help appreciated.

Hint: Look at size(kR) and size(phi). You also need to look at the other lines for your use of * vs .* operation, since it looks like you will have similar problems there as well.
