The manufacturer of a 2.1 mw wind turbine provides the power produced by the turbine (outputpwrdata) given various wind speeds (windspeeddata). linear and spline interpolation can be utilized to estimate the power produced by the wind turbine given windspeed.

assign outputpowerinterp with the estimated output power given windspeed, using a linear interpolation method. assign outputpowerspline with the estimated output power given windspeed, using a spline interpolation method.
ex: if windspeed is 7.9, then outputpowerinterp is 810.6 and outputpowerspline is 808.2.

function [ outputpowerinterp outputpowerspline ] = estimatewindturbinepower( windspeed )
% estimatewindturbinepower: estimates wind turbine output power using two interpolation methods
% inputs: windspeed - wind speed for power estimate
%
% outputs: outputpowerinterp - estimated output power using
% linear interpolation
% outputpowerspline - estimated output power using
% spline interpolation

windspeeddata = [ 0, 2, 4, 6, 7, 8, 9, 10, 12, 14, 16, 18, 20, 22, 24, 26,
28, 30 ]; % (m/s)
outputpwrdata = [ 0, 0, 14, 312, 546, 840, 1180, 1535, 2037, 2100, 2100,
2100, 2100, 2100, 2100, 0, 0, 0 ]; % (kw)

% assign outputpowerinterp with linear interpolation estimate of output power
outputpowerinterp = 0; % fixme

% assign outputpowerspline with spline interpolation estimate of output power
outputpowerspline = 0; % fixme
