# Synopsis

double mth_Get2DArea(long num_of_points, long ndim, double *points)

# Purpose

Get the area of a 2D point set assuming counterclockwise orientation.

# Description

Computes the area of a 2D closed point set assuming counterclockwise orientation will generate a postive area. Only the first two dimensional values for each point are used in the 2D area calculation. All other values are ignored.

# Input

## num_of_points

The number of points in the closed 2D point set.

## ndim

The number of dimensions the set of points. Must be greater than or equal to two.

## points

The point set.

# Return

The area of the enclosed set of points (positive area == counterclockwise orientation).
