The dot indicates element-wise as opposed to array operations.
See the documentation on Array vs. Matrix Operations for details.

In MATLAB, using a dot before certain mathematical operators is known as element-wise operations. When you write an equation like y = x.*z + c.^2, the dot before the multiplication (.*) and exponentiation (.^) operators indicates that the operations should be applied element-wise to arrays or matrices.
