# trapz

Numerical integration of discrete data using the trapezoid rule.

## Syntax

area=trapz(y)

area=trapz(x,y)

area=trapz(...,dim)

## Inputs

`x`- Values of the domain variable.
`y`- Values of the range variable.
`dim`- The dimension on which to integrate.

## Outputs

- area
- The estimated area.

## Example

`x = [0:0.05:1]*pi; area = trapz(x,sin(x))`

`area = 1.99588597`

## Comments

trapz is appropriate for use with sampled data when the function is not available.
