I would just like to know what the : operator does when used to plot in the following context:
plot(x,Tanal(:,Nt),
I can see that x is plot against Tanal for some values of Nt but cannot quite work out which is refers to.
Thanks

Ah OK, I see now. So by removing the : operating it plots all rows of data within the Tanal matrix. Thanks for your help
