# times, .*

Element-wise multiplication

## Syntax

``C = A.*B``
``C = times(A,B)``

## Description

example

````C = A.*B` multiplies arrays `A` and `B` element by element and returns the result in `C`.```
````C = times(A,B)` is an alternate way to execute `A.*B`, but is rarely used. It enables operator overloading for classes.```

## Examples

collapse all

Create two vectors, `A` and `B`, and multiply them element by element.

```A = [1 0 3]; B = [2 3 7]; C = A.*B```
```C = 2 0 21 ```

Create two 3-by-3 arrays, `A` and `B`, and multiply them element by element.

```A = [1 0 3; 5 3 8; 2 4 6]; B = [2 3 7; 9 1 5; 8 8 3]; C = A.*B```
```C = 2 0 21 45 3 40 16 32 18 ```

Create a row vector `a` and a column vector `b`, then multiply them. The 1-by-3 row vector and 6-by-1 column vector combine to produce a 6-by-3 matrix with all combinations of elements multiplied.

`a = [1 2 3]`
```a = 1 2 3 ```
`b = (1:6)'`
```b = 1 2 3 4 5 6 ```
`a.*b`
```ans = 1 2 3 2 4 6 3 6 9 4 8 12 5 10 15 6 12 18 ```

## Input Arguments

collapse all

Left array, specified as a scalar, vector, matrix, or multidimensional array. Numeric inputs `A` and `B` must either be the same size or have sizes that are compatible (for example, `A` is an `M`-by-`N` matrix and `B` is a scalar or `1`-by-`N` row vector). For more information, see Compatible Array Sizes for Basic Operations.

If `A` and `B` are datetime, duration, or calendar duration arrays, then they must be the same size unless one is a scalar.

Data Types: `single` | `double` | `int8` | `int16` | `int32` | `int64` | `uint8` | `uint16` | `uint32` | `uint64` | `logical` | `char` | `categorical` | `duration` | `calendarDuration`
Complex Number Support: Yes
