Creating a Traffic Light using matlab code

Hello everyone,

I have matlab 2015b. I wrote a code for an assignment that categorizes a dataset as healthy, aged, and replace.

Part of my assignment is to create a horizontal visual dashboard. Basically like a traffic stop light. The traffic light needs to light up green for healthy, yellow for aged, and red for replace based on the point that is being evaluated.

Is this something I would use simulink for or GUI or is it simplier than I think in matlab?

Any help is greatly appreciated.

clear all

close all

clc

load('ThreeClasses')

for i = 1:size(TestPoints,1)

X=TestPoints(i,2);

Y=TestPoints(i,3);

Delta1=log(P1)-0.5*mu1*inv(Sw)*mu1'+mu1*inv(Sw)*[X;Y];

Delta2=log(P2)-0.5*mu2*inv(Sw)*mu2'+mu2*inv(Sw)*[X;Y];

Delta3=log(P3)-0.5*mu3*inv(Sw)*mu3'+mu3*inv(Sw)*[X;Y];

if Delta1 > Delta2 && Delta1 > Delta3

plot(X,Y,'g.','markersize',30);

elseif Delta2 > Delta1 && Delta2 > Delta3

plot(X,Y,'y.','markersize',30);

else

plot(X,Y,'r.','markersize',30);

end

pause(1)

end

Use of GUI to show as red, yellow and green will be more preferable for visual demonstration.
