# sinh

Returns the hyperbolic sine of `a` (input in radians).

## Syntax

sinh(a)

## Inputs

`a`- Any valid scalar | vector | matrix in radians.

## Outputs

- R
- scalar | vector | matrix

## Examples

`R = sinh(-0.5)`

`R = -0.521095`

`R = sinh([-3,.6])`

`R = [ -10.0179 0.636654 `

`R = sinh([i+2,3i-1;i,0.3])`

`R = [ 1.9596 + 3.16578i, 1.16344 + 0.21776i; 0.841471i, 0.30452]`
