I am trying to make a graph with a function.
This is my graph
I need it to look like this graph
Here is my function
function [turbinePower] = windTurbineModel(windSpeed,deltaT,cD,k)
%variables
cTau = 0.042;
vRated = 11.5;
vCutin = 3;
vCutout = 25;
D = 171;
J = 100e5;
time = 0:deltaT:300;
%wind and rotational variables
rotationalSpeeds = zeros(length(windSpeed),1);
rotorTorque = zeros(length(windSpeed),1);
generatorTorque = zeros(length(windSpeed),1);
turbinePower = zeros(length(windSpeed),1);
rotorAcc = zeros(length(windSpeed),1);
for i = 2:length(time)
rotorTorque(i) = windTurbineRotorModel(windSpeed(i),cTau,D,vCutin,vCutout,vRated);
generatorTorque(i) = k*((rotationalSpeeds(i-1))^2);
rotorAcc(i) = (rotorTorque(i)-generatorTorque(i)-cD*rotationalSpeeds(i))/J;
rotationalSpeeds(i) = rotationalSpeeds(i-1) + deltaT*(rotorAcc(i))./J;
turbinePower(i) = generatorTorque(i)*rotationalSpeeds(i);
end
end
and here is my graph code
close all
clear
%variables
k=6*10.^(1:1:10);
Cd = 1.5*10.^(1:1:8);
deltaT = 0.01;
time = 0:deltaT:300;
turbinePowerMean = zeros(length(Cd),length(k));
turbinePowerStd = zeros(length(Cd),length(k));
%------------------Do not edit these lines---------------------------------
windTimeSeries = wblrnd(13,2.10,size(time'));
windTimeSeries = medfilt1(windTimeSeries,50,'truncate');
%-------------------------------------------------------------------------
for i = 1:length(k)
for ii = 1:length(Cd)
turbinePower = (windTurbineModel(windTimeSeries,deltaT,Cd(ii),k(i)));
turbinePowerMean(ii,i) = mean(turbinePower);
turbinePowerStd(ii,i) = std(turbinePower);
end
end
subplot(1,3,1);
h1 = heatmap(k,Cd,turbinePowerMean/7e6);
title("Mean Power Output for varying k and C_d");
ylabel("Damping coeff kg m^3 s^-^1");
xlabel("Generator control Gain, k");
subplot(1,3,2);
heatmap(k,Cd,turbinePowerStd/7e6);
subplot(1,3,3);
heatmap(k,Cd,turbinePowerMean./turbinePowerStd);

Not sure I understand what you need.
To make your figure as close as the target, you can try to:
- add titles and axis labels for subplots 2 and 3
- set the background of the figure to white [set(gcf, 'color', 'white');]
- resize the figure vertically
If you are talking about the colour of the boxes, then you need to verify your data and make sure they are the same for both figures.
