Plot a vector with different colors on selected data

Hi community,

I have a vector of 700 elements. While plotting, I want to plot first 100 points in 'Red' color and the next 100 points in 'Blue' color. Later, I want to repeat them. Is there any inbuilt function to do it?

Thanks

No loops needed:

v = reshape(vector,100,[]);
plot(v(:,1:2:end),'r')
hold on
plot(v(:,2:2:end),'b')

Thanks Madhan. But, I do not want them to overlap. I want to have 700 points on X-axis with alternate red and blue colors. Hope I was clear.

Not sure what you mean , perhaps add markers:

'or' & 'ob'

@Madhan: Something like this

Just add x data

x = linspace(0,30,700);
y = sin(x);
x1 = reshape(x,100,[]);
y1 = reshape(y,100,[]);
i1 = 1:2:size(x1,2);
i2 = 2:2:size(x1,2);
plot(x1(:,i1),y1(:,i1),'r')
hold on
plot(x1(:,i2),y1(:,i2),'b')
hold off
