wflo (version 1.9)

Height: Returns the elevation of a turbine's location.

Description

For a turbine's location represented by x and y, looks up the elevation from the matrix Elev. Internally transforms coordinates of x and y from problem space (usually unit square) to the matrix space of Elev.

Usage

Height(x, y, Elev)

Value

Height returns a single value, the elevation in meters.

Arguments

x

must be a single value containing the 'x' location of a turbine in problem space.

y

must be a single value containing the 'y' location of a turbine in problem space.

Elev

a matrix containing heights. Usually, the fifth element of the list object FarmData will be used as this matrix.
