how to loop it

I have two columns. Both columns reads 264 elements and lets call them x & y.

x= 264*1 % reads radius r

y =264*1 % reads angle theta

I want to multiply first element of x with 1st element of y & 2nt elemnt of x with 2nd elemnt of y. How to do it... I used this logic. Its not working... Please help me

for i = 1 :264

x_new = x(i) * cosd(y(i))

y_new = y(i) * sind(y(i))

end

Use the multiplication element by element .*

z=x.*y
x_new=x.*cosd(y)
y_new=y.*sind(y)

Thank You. Iam getting it now :)

Change:

 x_new = x(i) * cosd(y(i))
 y_new = y(i) * sind(y(i))

to

 x(i+1) = x(i) * cosd(y(i))
 y(i+1) = y(i) * sind(y(i))
