Description Usage Arguments Details Value Author(s) Examples
Determines area of a polygon by triangle method. The variables
x
and y
define the vertex pairs, and must therefore
have the same shape. They can be either vectors or arrays. If
they are arrays then the columns of x
and y
are
treated separately and an area returned for each.
1 | polyarea(x, y, d = 1)
|
x |
X coordinates of verticies. |
y |
Y coordinates of verticies. |
d |
Dimension of array to work along. |
If the optional dim
argument is given, then polyarea
works along this dimension of the arrays x
and y
.
Area(s) of polygon(s).
