Area of polygon

Syntax

Description

A = polyarea(X,Y) returns the area of the polygon specified by the vertices in the vectors X and Y.

If X and Y are matrices of the same size, then polyarea returns the area of polygons defined by the columns X and Y.

If X and Y are multidimensional arrays, polyarea returns the area of the polygons in the first nonsingleton dimension of X and Y.

A = polyarea(X,Y,dim) operates along the dimension specified by scalar dim.
