MATLAB supports (and encourages) vectorized operations on vectors and matrices.

For example, suppose we have `A`

and `B`

, two `n`

-by-`m`

matrices and we want `C`

to be the element-wise product of the corresponding elements (i.e., `C(i,j) = A(i,j)*B(i,j)`

).

The un-vectorized way, using nested loops is as follows:

```
C = zeros(n,m);
for ii=1:n
for jj=1:m
C(ii,jj) = A(ii,jj)*B(ii,jj);
end
end
```

However, the vectorized way of doing this is by using the element-wise operator `.*`

:

```
C = A.*B;
```

- For more information on the element-wise multiplication in MATLAB see the documentation of
`times`
