Error with using the multiplication sign

I have this code:

final_ans = (1/(4*pi*(8.85*(.0000000000001))))*(y/(t*t));

but matlab will not compute it because it says "Incorrect dimensions for matrix multiplication", even though I am not multiplying a matrix. How do I fix it?

Your t is a vector so t*t is matrix multiplication between t and itself. You need t.*t or t.^2

However you will need another change as well. (y/(t*t)) will not (y./(t.*t)) or (y./t.^2)
