# pow2

Computes powers of 2.

## Syntax

R = pow2(X)

R = pow2(F, E)

## Inputs

`X`- Specifies the desired power of two to return.
`F`- The number to multiply by 2.^
`E`. `E`- The exponent. Must have the same dimensions as
`F`.

## Outputs

- R
- The result of either 2.^X or F.*2.^E.

## Examples

Simple scalar
input:

`R = pow2(4)`

`R = 16`

Simple matrix
input:

`R = pow2([4 3])`

```
R = [Matrix] 1 x 2
16 8
```

Multiple scalar input with pow2(2,3) being equivalent to 2 *
2^3:

`R = pow2(2,3)`

`R = 16`

Multiple matrix
input:

`R = pow2([2.2,7.7,1.1],[-3,1.8,2.3])`

```
R = [Matrix] 1 x 3
0.27500 26.81296 5.41704
```
