Hi, I tried executing this loop,
colors = ['m';'y';'b';'g';'c'];
loop_ind = 1;
for k1 = 1:5
figure(4);
linespec = colors(loop_ind);
plot(x, y, linespec, 'LineWidth', 1);
loop_ind = loop_ind + 1;
hold on
end
legend('-0.02','-0.01','0','0.01','0.02')
But I get an error,
Attempted to access colors(6); index out of bounds because numel(colors)=5. Error in test_contact_ellipse (line 228)
linespec = colors(loop_ind);
Now I'm getting the plot with the correct colors but the legend doesn't appear. How can I rectify this error.
Please give your suggestions.
Thanks

This is an example that plots in different colors with a matching legend:
c = [0 1 0; 1 0 0; 0 0 1; 1 0 1; 0 1 1];
x = linspace(0,2*pi);
figure(4)
hold on
for k1 = 1:size(c,1)
plot(x, sin(x*k1)+k1, 'Color', c(k1,:))
end
hold off
grid
legend('Color 1', 'Color 2', 'Color 3', 'Color 4', 'Color 5')
Adapt it as necessary to your application.

In the last loop, replace with the following and see if it is what you are looking for:
figure(4);
plot(x, y, 'LineWidth', 1,'color',colors(k2))
axis square;
axis equal;
grid on;
xlabel('Longitudinal');ylabel('Lateral');title('Contact ellipse shape');
hold on
myh = line([xCenter, xCenter], [yCenter - yRadius(k2), yCenter + yRadius(k2)], ...
'LineWidth', 1, 'Color', [1,0,0]);
set(get(get(myh,'Annotation'),'LegendInformation'),'IconDisplayStyle','off');
myh = line([xCenter - xRadius(k2), xCenter + xRadius(k2)], [yCenter, yCenter], ...
'LineWidth', 1, 'Color', [1,0,0]);
set(get(get(myh,'Annotation'),'LegendInformation'),'IconDisplayStyle','off');
It seems that some of your ellipses are overwritten with others. Since I don't know what you are doing, this is the best I can recommend. I'd replace also:
for k2 = 1:size(a,2)
