plotting matrix of unknown size

Hi, I am programming a semiconductor characterization system and I need to plot a matrix consisted of data.

The problem is that my script does not know how many curves it should plot before the program execute.

For example if the user decides to have k curves, then the program will generate matrix M of size 255 by 3*k.

Now I need to tell Matlab to plot curves where X is M(:,3*i+2) and Y is M(:,3*i+1) for i = 0 : k-1.

Is there a simple way to tell this to Matlab? Maybe for loop inside the plot function?

I hope my explanation was clear.

plot( M(:,2:3:3*k-1), M(:, 1:3:3*k-2) )
