I've tried to plot the following wind rose problem bu I can not get the right answer. Please advise how to do this problem. I am working on this code. Why can't I obtain the rose provided?

v=[5 15 4; 1 0 0; 13 5 3; 7 0 0; 10 1 2; 11 0 0; 19 2 1; 1 0 0]; %Percentage of winds
d=[0 0 0; 45 45 45; 90 90 90; 135 135 135; 180 180 180; 225 225 225; 270 270 270; 315 315 315]; %Wind directions
% v = sort(v); %Wind speeds
% d=[0 30 60 90 120 150 180 210 240 270 300 330 ]; %Wind directions
%Execute wind rose function
wind_rose_Example(d,v)
function wind_rose_Example(wind_direction,wind_speed)
%WIND_ROSE Plot a wind rose
% this plots a wind rose

pax = polaraxes;
polarhistogram(deg2rad(wind_direction(wind_speed<47)),deg2rad(0:10:360),'FaceColor','red','displayname','31 - 47 MPH')
hold on
polarhistogram(deg2rad(wind_direction(wind_speed<31)),deg2rad(0:10:360),'FaceColor','yellow','displayname','15 - 31 MPH')
polarhistogram(deg2rad(wind_direction(wind_speed<15)),deg2rad(0:10:360),'FaceColor','green','displayname','4 - 15 MPH')
pax.ThetaDir = 'clockwise';
pax.ThetaZeroLocation = 'top';

%to add percentages
% numberOfMeasurement = sum(wind_speed<20);
% p = 1:10;
% rticks(p/100*numberOfMeasurement)
% rticklabels(strcat(string(p),'%'))
% rlim([0 10/100*numberOfMeasurement])
end
