Incorrect Dimensions in Matrix Multiplication

Any help would be appreciated.

x = 0:0.05:3;

v = 1.062*10^-8*x.^(2)*exp(-2.81*10^-6*x.^2);

plot(x,v)

returns

Error using *

Incorrect dimensions for matrix multiplication. Check that the number of columns in the first

matrix matches the number of rows in the second matrix. To perform elementwise multiplication,

use '.*'.

Missing a dot!

x = 0:0.05:3;
v = 1.062*10^-8*x.^(2).*exp(-2.81*10^-6*x.^2);
plot(x,v)
