How to make equally spaced symbols on a line plot

I have a line plot (created from an array with many many points) and I want to use symbols rather than colours to indicate the different data. Does anyone know how to do this?
I know you can't simply add 'o' at the end because this gives error message 'The end operator must be used within an array index expression'
Cheers!

Do you want something like this?
x = 1:100;
y = sin(x/10);
plot(x,y) % the whole line
hold on
plot(x(1:10:end),y(1:10:end),'bo') % markers every so often

Instead of this:
plot(s9a(end-1000:10:end,1)*10^-6, s9a(end-1000:10:end,3)*10^9,'Color',c(5,:), 'o')
Do this:
plot(s9a(end-1000:10:end,1)*10^-6, s9a(end-1000:10:end,3)*10^9,'o','Color',c(5,:))
Property/Value pairs, like 'Color',c(5,:), must come at the end of the list of arguments to plot.
